The best gaming motherboard will be the unsung hero of your PC. Like a good rug, the best motherboards will really tie your PC together, but with so little difference in performance between mobos they can often feel like an afterthought. Or else just a place you can save a few bucks to spend on a better CPU or graphics card.

Best gaming monitor: pixel-perfect panels for your PC
Best 4K monitor for gaming: when only high-res will do
Best 4K TV for gaming: big-screen 4K PC gaming

That's not a bad shout for a pure gaming PC, where frame rates are the one true god. But even then it's important to make sure that you're not missing out on some important functionality you could ill do without, or come to regret skimping out on. Do you want the option to overclock your CPU at some point, or do you need high-performance memory support. Replacing your motherboard down the line is a serious business, and not something to be taken lightly. 

When picking your perfect motherboard you need to know which processor you're going to be building your new rig around. Are you resolutely tying yourself to the mast of the good ship Intel, as it ploughs on through the roughest waters it's known? Or are you going to proudly fly the flag of AMD? Given the performance of the new AMD Ryzen 5000 CPUs, I know where I'd be putting my money...

The best gaming motherboards can also offer a modicum of future-proofing, as much as anything can in this fickle, fast-moving PC technology landscape of ours. Whether that's a socket or chipset which is capable of supporting tomorrow's new processors, such as the Intel's Z490 and Rocket Lake chips, or one that's able to deliver next-gen interconnects, such as the B550's PCIe 4.0 support.

Size is also of vital importance too. If you're just building out a standard ATX scale gaming PC, then pretty much any motherboard is open to your whims, but if you want to go for a smaller chassis, either Micro ATX or Mini ITX, then you'll need a corresponding mobo. That doesn't necessarily mean sacrificing performance or key features anymore. A single PCIe slot is more than enough for today's SLI/CrossFire-less GPU world, and even some Mini ITX boards will come with multiple M.2 SSD slots.

The scale will impact pricing, however. Interestingly Micro ATX boards are often the most affordable, while Mini ITX options can be among the most expensive. We've picked our top two favourite gaming motherboards, for each of the main Intel and AMD chipsets, to give you the best options around.

Best Intel Z490 motherboard

1. Asus ROG Maximus XII Extreme

The best board for a Comet Lake Core i9... and for showing off.

CPU support: Intel 10th Gen | Socket: LGA 1200 | Size: Extended ATX | Memory support: 4x DIMM, up to 128GB, DDR4-4700 | Expansion slots: 2x PCIe 3.0 x16 (or x8/x8), 1x PCIe 3.0 x4 | Video ports: 2x Thunderbolt 3 ports on extension card (DP1.4) | Rear USB: 10x USB 3.2, 2x USB 2.0 | Storage: 2x M.2, 2x M.2 (DIMM.2 board), 8x SATA 6Gbps | Network: 1x 10Gb Marvell ethernet, 1x Intel ethernet, Intel Wi-Fi 6 wireless

High-end performance
Stunning bundle
Incredible build quality

If you want the best, most fully featured Intel Comet Lake motherboard then I'm afraid you're going to have to pay for it. And pay through the nose if Asus' Z490 Maximus XII Extreme is anything to go by. It is, as the name suggests, extreme, packing in a variety of luxurious, and incredibly handy extras (a frickin' screwdriver with interchangeable heads for one), and it's also one of the highest performing Z490 boards we've tested.

But it only really makes sense if you're buying a K-series Core i9 and genuinely intend to overclock the nuts off it. The Maximus XII will allow you to get the highest clock speed out of your 10900K and won't turn it into a pile of molten slag while you're at it. The MSI Z490 Godlike is actually the fastest Z490 outright at stock speeds, but I'd rather have the ROG board in my camp if I'm going down the OC route.

Obviously it's only for the very highest of high-end PC builds, however, as the $750 price tag means you could actually build a respectable full gaming PC for the price of this single motherboard. It's an aspirational Z490 motherboard, and arguably the best gaming motherboard for Comet Lake overclocking, but I'll concede it's not a particularly realistic purchase for most of us.

2. MSI MPG Z490 Gaming Carbon WiFi

A vaguely affordable Z490 motherboard with competitive performance.

CPU socket: Intel 10th Gen | Socket: LGA 1200 | Size : ATX | Memory support: 4x DIMM, up to 128GB, DDR4-4800 (OC) | Expansion slots: 3x PCIe 3.0 (x16/x0/x4 or x8/x8/x4), 2x PCIe 3.0 x1 | Video ports: 1x DisplayPort, 1x HDMI | Rear USB: 5x USB 3.2, 2x USB 2.0 | Storage: 2x M.2, 6x SATA 6Gbps | Network : 1x 2.5Gb LAN, Intel Wi-Fi 6 wireless

 More reasonably priced Z490 
 Still competitive performance 

The sparse back panel and missing OLED displays will tell you we're back into normal motherboard territory again. The rarified air of the ultra-enthusiast ROG board up top might make one giddy, but the Z490 Gaming Carbon will bring us back down to earth without a bump. Sure, you're never going to get the same level of luxury feature list as you'll find with either the Maximus XII or MSI's own Godlike boards, but when it comes to the nuts and bolts of pure performance it's right up there. 

Where it matters, in the gaming performance stakes, there's practically nothing between any of the Z490 boards we've tested, and it's only ever a little behind when it comes to the actual CPU performance in productivity apps. When it comes to overclocking, however, the MPG Z490 Gaming Carbon WiFi inevitably can't compare to the big boys with our 10900K running at its peak.

The power componentry and cooling isn't enough to stop the thirsty CPU from throttling when it's pushed to its 5.3GHz all-core maximum. But, while that might mean it's not the board you'd choose for an overclocked i9 machine, that's a tiny niche of gamers, and for either i5 or i7 CPUs the MSI Gaming Carbon is still a quality home for your Comet Lake CPU.

Best Intel B460 motherboard

1. MSI MAG B460M Mortar WiFi

A premium mATX B460 offering without the exorbitant pricetag.

CPU support: Intel 10th Gen | Socket: LGA 1200 | Size: Micro ATX | Memory support: 4x DIMM, up to DDR4-2933 (i7,i9) or DDR4-2666 (i5) | Expansion slots: 2x PCIe 3.0 x16, 1x PCIe 3.0 x1 | Video ports: 1x DisplayPort, 1x HDMI | Rear USB: 4x USB 3.2 Gen (1x Type-C), 2x USB 2.0 | Storage: 2x M.2, 6x SATA 6Gbps | Network: Realtek 2.5Gb LAN, Intel Wi-Fi 6 wireless

Great value
Strong VRM
Quality I/O and connectivity

Grabbing one of the best Z490 motherboards might be appealing to your inner elitist, but the sticker price shock is definitely a problem for a lot of people. Sure, it would be nice to have 10Gb LAN, seven M.2 slots, or quad GPU support, but who really needs all that stuff? Most of us will be perfectly happy with a quality B460 motherboard, such as the MSI MAG B460M Mortar WiFi. 

If you can put up with the memory speed limitation and have no intention of overclocking (well, with a K-series CPU anyway) then this is the kind of board that should be on your PC building wishlist. It ticks most of the important boxes and at $125 it’s well priced, though the competition is tough with many premium B460 motherboards priced in this range.

It’s got a strong VRM, 2.5Gb LAN, Wi-Fi 6, and adequate, if not particularly outstanding I/O. Pairing it with a 65W non-K processor and having a crack at pseudo overclocking is definitely worth the minimal efforts too. If you can live with the maximum DDR4-2666 speed, then something like an Intel Core i5-10600 and B460M Mortar, paired with a decent mid-range GPU, would deliver a quality, and affordable, gaming combo.

2. ASRock B460 Steel Legend

An affordable and attractive B460 board that's got it where it counts.

CPU support: Intel 10th Gen | Socket: LGA 1200 | Size: ATX | Memory support: 4x DIMM, up to DDR4-2933 (i7,i9) or DDR4-2666 (i5) | Expansion slots: 2x PCIe 3.0 x16, 1x PCIe 3.0 x1 | Video ports: 1x DisplayPort, 1x HDMI | Rear USB: 4x USB 3.2 Gen (1x Type-C), 2x USB 2.0 | Storage: 2x M.2, 6x SATA 6Gbps | Network: Realtek 2.5Gb LAN

Quality VRM
Good value for money
Strong performance

The ASRock B460 Steel Legend is an awesomely named mid-range B460 entry. At $120 USD it’s what we’d call a mid-range B460 board. A look over the specs indicate that your $120 is well spent on some important areas. You get a pair of heatsink covered M.2 slots, an e-key M.2 slot for an optional Wi-Fi card, a front USB Type-C header and a good helping of RGB onboard.

The increased power demands of 10th generation CPUs means motherboards generally have to include improved VRM designs, and on that front the B460 Steel Legend is very well equipped. It includes a 9+1 phase VRM powered by a single 8-Pin EPS connector. Each stage can deliver up to 60A. Bear in mind that overclocking is not allowed on B460 motherboards, so the VRM will not see extreme loads like you might get with an all core overclocked Intel Core i9 10900K

The ASRock B460 Steel legend will appeal to buyers who aren’t so interested in bells and whistles, but do want a solid ATX board that’s capable of powering any 10th Gen CPU without bursting into flames. Integrated Wi-Fi would have been a nice cherry on top for the price, and that's arguably one of the reasons we prefer the MSI B460M Mortar. But the ASRock B460 Steel legend is still a highly competitive offering and comes highly recommended by us too. It shows its steel, one might say. If it had Wi-Fi we might even have said it was legendary.

1. Gigabyte Z390 Aorus Ultra

The best gaming motherboard for Intel's last-gen CPUs.

CPU support: Intel 8th and 9th Gen | Socket : LGA 1151 | Size: ATX | Memory support: 4x DIMM, up to 128GB, DDR4-4400 (OC) | Expansion slots: PCIe x16, PCIe x16 (x8), PCIe x16 (x4), 3x PCIe x1 | Video ports: HDMI | Rear USB: 4x USB 3.2 Gen2 (1x Type-C), 2x USB 3.1 Gen1, 4x USB 2.0 | Storage: 3x M.2, 6x SATA | Network: Ethernet, 1.73Gbps 802.11ac wireless

No-compromise features, including triple M.2 slots
Slick RGB package with two LED headers

The Gigabyte Z390 Aorus Ultra competes with the MSI Z390 Gaming Pro Carbon AC and the Asus ROG Maximus XI Hero (Wi-Fi), but with a lower price tag and more features. It has triple M.2 slots for your super-speedy NVMe SSD needs, Intel Wi-Fi Wave2 and ethernet, a full RGB treatment with multiple headers, and ALC1220 audio. You'd have to climb right to the top of the product stack to get the same from MSI and ASUS, both of whom offer a little more polish, but also charge plenty for the privilege. Though there's a lot to be said for extreme motherboards, this is a great value Intel board.

The only real downside for us is that this mobo is perhaps a little too flashy and may not suit more restrained gaming builds. Thankfully, you can disable all the RGB bling within the BIOS if you want, though other elements may still clash. But that's a small criticism of an otherwise top board.

2. Asus ROG Strix Z390-I Gaming

Best for small form-factor Intel 9th-gen builds.

CPU support: Intel 8th and 9th Gen | Socket: LGA 1151 | Size: Mini-ITX | Memory support: 2x DIMM, 64GB, DDR4-4800 (OC) | Expansion slots: 1x PCIe x16 | Video ports: HDMI 2.0, DisplayPort 1.2 | USB ports: 7x rear IO, 1x front IO, 4x internal | Storage: 2x M.2, 4x SATA | Network: Ethernet, 866Mbps 802.11ac | Lighting: Edge RGB, 1x Addressable Aura RGB

Dual M.2 slot
Great overclocking and system performance

With the price dropping and the previous Z370-based model disappearing from vendors, ASUS's Strix Z390-I Gaming moves into the top spot for the boutique ITX segment. Despite its diminutive size, and paucity of upgrade options, the ROG Strix Z390-I Gaming provides excellent performance and value. Boasting stable 5GHz overclocks using several memory speeds, including 3,600MHz with tweaking, its single PCIe x16 slot pushed top-shelf graphics cards to speeds that matched or exceeded most Z390 ATX boards during testing.

The smallest Strix has a lengthy features list, with no shortcomings despite the tiny form factor, including dual PCIe Gen3 x4 M.2 slots, Intel v219 ethernet, upgraded Intel 9560 2x2 802.11ac Wi-Fi, and an ALC1220A audio codec supported by isolated circuitry and headphone amps. Despite the dense set of features, the Strix Z390-I's clean design makes for quick system assembly and configuration, an important consideration for ITX rig building. 

It's worth noting that this board can be hard to find, but the previous generation ROG Strix Z370-I model, with its slimmer design, remains an excellent alternative, especially at clearance prices.

1. MSI MPG X570 Gaming Pro Carbon WiFi

The best gaming motherboard for AMD Ryzen 3000 builds.

CPU support: AMD 2nd, 3rd, and 4th Gen Ryzen CPUs, Ryzen APUs | Socket: AM4 | Size: ATX | Memory: 4x DIMM, 128GB, DDR4-4400 | Expansion slots: 1x PCIe x16, 1x PCIe x16 (x4), 2x PCIe x1 | Video ports: HDMI | Rear USB: 4x USB 3.2 Gen2 (1x Type-C), 2x USB 3.2 Gen1, 2x USB 2.0 | Storage: 2x M.2, 6x SATA | Network: Ethernet, 2.4Gbps 802.11ac

2 PCIe 4.0 M.2 Slots
Wi-Fi 6 Compatible

The MSI MPG X570 represents an amalgamation of bleeding-edge motherboard tech, built to get the most out of AMD's 3rd gen Ryzen CPUs. It has four DIMM slots that can handle speeds up to 4,400Mhz and two M.2 slots sporting support for PCIe 4.0.

The rear I/O panel features seven USB-A ports for peripherals, as well as a single USB-C port for connectivity and high-speed data transfer. There are headers for the included Wi-Fi antenna to help with wireless connectivity, as well as a gigabit ethernet port. The MPG X570 supports Wi-Fi 6, and while that does necessitate a Wi-Fi 6 compatible router, it's backward compatible with other Wi-Fi standards and gives the potential for a speed boost down the line. Also of note is the HDMI port, which many X570 boards omit (not that we'd really recommend using an AMD APU with integrated graphics in a high-end board like this).

The MPG X570 features enough compatibility to get the most out of your hardware now and in the future, provided you're willing to pay a premium for it. While it's certainly an excellent mobo, if you aren't already committed to a shopping list of top-of-the-line components now or in the near future, you may want to consider a slightly less expensive board for your needs.

2. Gigabyte X570 Aorus Master

The best high-end AMD board for overclocking.

CPU support: AMD 2nd, 3rd, and 4th Gen Ryzen CPUs, Ryzen APUs | Socket: AM4 | Size: ATX | Memory support: 4x DIMM, 128GB, DDR4-4400 (OC) | Expansion slots: 1x PCIe x16, 1x PCIe x16 (x8), 1x PCIe x16 (x4), 2x PCIe x1 | Video ports: None | Rear USB: 4x USB 3.2 Gen2 (1x Type-C), 2x USB 3.2 Gen1, 4x USB 2.0 | Storage: 3x M.2, 6x SATA | Network: 1x Intel GbE LAN, 1x Realtek 2.5GbE LAN, 802.11ax Wi-Fi

Excellent performance
Great networking options
Reliable and sturdy design

This X570 motherboard remains one of the best options for any high-end AMD Zen 2 or Zen 3 build. There are a few reasons for this, but the three M.2 slots, great wired and wireless networking, and expansion possibilities top the list. Yes it's one of the more expensive options, but you really do get a lot of motherboard for your money, and it's utterly reliable too.

The 14-phase VRM design ensures your CPU is getting lots of clean power, which in turn makes this one of the best options for overclocking your Ryzen 3000 or Ryzen 5000 processor of choice. All that metal atop of the VRMs helps keep things cool, as does the massive plate that covers the rear of the board. The M.2 slots all have heat spreaders, and the expansion and memory slots are reinforced to.

The only real mark against it, other than the price, is that if you do use all three M.2 slots you only get four SATA ports to play with. Still, this is a sturdy and well thought out board that will serve you well.

Best AMD B550 motherboard

(Image credit: Asus)

1. Asus ROG Strix B550-E Gaming

Simply the best B550 motherboard.

CPU support: AMD 3rd and 4th Gen Ryzen | Socket: AM4 | Size: ATX | Memory support: 4x DIMM, up to 128GB, up to DDR4-4600 | Expansion slots: 2x PCIe 4.0 x16, 1x PCIe 3.0 x4 | Storage: 2x M.2, 6x SATA 6Gbps | Networking: Intel Wi-Fi 6, Intel 2.5Gb ethernet, Bluetooth 5.1 | Rear USB: 3 x USB 3.2 Gen 2, 4 x USB 2.0

Extensive feature set
Build quality
Top-end networking

Sure, the Asus ROG Strix B550-E is the same price as other X570 motherboards, in fact it pretty much matches our favourite of AMD's top-end boards, the MSI MPG X570 Gaming Pro Carbon. But it's a premium motherboard, with all the trappings you'd expect from Asus' Republic of Gamers stable, such as 14+2 power stage, M.2 heatsinks, and pre-installed backplates. You also get Wi-Fi 6 wireless networking as well as Intel 2.5Gb ethernet too. And RGB LEDs, of course. If you're looking at building a Zen 3 system, then the necessary BIOS updates should drop in January for this motherboard.

Performance too is typically good for a high-end Asus board, matching X570 motherboards for gaming performance without issue. That said, of the B550 boards we've tested, it's the far more affordable MSI board that actually comes out top in our straight performance testing. But the Asus can overclock far better, even if it does chew up more raw power from the plug on the whole.

The Asus ROG Strix B550-E Gaming is the whole package then, and right now is our all-round pick for the best B550 motherboard. Though that still feels like a tough recommendation when X570 boards are the same price…

2. MSI MAG B550M Mortar

The best B550 motherboard for pure gaming performance.

CPU support: AMD 3rd and 4th Gen Ryzen | Socket: AM4 | Size: Micro-ATX | Memory support: 4x DIMM, up to 128GB, up to DDR4-4400 | Expansion slots: 1x PCIe 4.0 x16, 1x PCIe 3.0 x4 | Storage: 2x M.2, 6x SATA 6Gbps | Networking: Realtek 2.5Gb ethernet | Rear USB: 2 x USB 3.2 Gen 1, 1 x USB 3.2 Gen 2, 1 x USB 3.2 Gen 2 Type-C, 2x USB 2.0

Great stock-clock performance and efficiency
Slick BIOS
Competitive pricing

When it comes to gaming performance above all else then MSI's micro-ATX MAG B550M Mortar is your best bet for an affordable next-gen Ryzen machine. It comes in around the $160 mark, making it cheaper than a great many X570 and other B550 motherboards on the market right now. 

The gaming frame rates of the MSI B550 Mortar put it above the rest of the B550 crew we've tested so far, and indeed its straight CPU performance puts it up there with some of the best X570s. That bodes well if you're looking for an affordable home for your AMD Zen 3 CPU of the future (BIOS updates to support Ryzen 5000 chips are due to start rolling out in January), this B550 has a great chance to ensure it performs to its fullest stock-clocked potential without breaking the bank.

But you will be missing out on extra PCIe 4.0 M.2 and x16 graphics slots if those extras mean a lot to you. You can also opt to ditch wireless networking too, depending on whether you pick the straight Mortar or the more expensive Mortar Wi-Fi version. The 8+2+1 power phase design is arguably a more unwelcome miss, however, as that results in a board that isn't going to spark any overclocking joy in your heart. But, as an affordable gaming board without OC pretensions, it's a great shout.

Best AMD A520 motherboard

(Image credit: ASRock)

1. ASRock A520M ITX/ac

One for AMD's mini-ITX fans on a mini budget.

CPU support: AMD 3rd and 4th Gen Ryzen | Socket: AM4 | Size: Mini ITX | Memory support: 2x DIMM, up to 64GB, up to DDR4-4600 (OC) | Expansion slots: 1x PCIe 3.0 x16 | Video ports: 1x HDMI 2.1, 1x DVI-D | Storage: 1x M.2, 4x SATA 6Gbps | Networking: Realtek GbE LAN, Intel 802.11ac Wi-Fi | Rear USB: 4x USB 3.2 Gen1 (1x Type-C), 2x USB 2.0

Good value for money
Wi-Fi included
Ryzen 5000 support

AMD's budget Ryzen motherboard chipset, the A520, has largely slipped under the radar. While B350 and B450 motherboards were mostly regarded as being entry level, A320 was strictly seen as resolutely low end. 

The introduction of B550 motherboards, and their associated move upward in price, left a big hole in the sub-$100 market. Enter A520. If you’re on a tighter budget, and don’t care about PCIe 4.0 or the overclocking support offered by B550, then the A520 motherboards might be exactly what you need. There’s cheap and there’s really cheap, but a decent A520 board can more or less do everything a board at double the price can. 

Then there’s the cherry on top which is support for AMD Ryzen 5000 series CPUs and, almost as importantly, Ryzen 4000 series APUs. Combine a Zen 3 CPU with a motherboard such as this ASRock A520M ITX/ac and you’ll be able to build an affordable and compact system that can beat any Intel chip in any kind of workload.

The ASRock A520M's audio is a bit of a letdown but that’s something that budget boards often compromise on. A gamer listening to compressed audio assets in-game probably won’t be any less immersed. The little ASRock A520M ITX/ac has it where it counts and will serve you well at the heart of a budget gaming system. It benefits from the strengths of the Ryzen platform and adds some future proofing into the mix. ITX fans looking for a capable budget AMD Ryzen option should definitely have this one on their shortlist.

2. Gigabyte A520 Aorus Elite

The A520 Aorus Elite might be cheap, but it's definitely not nasty.

CPU support: AMD 3rd and 4th Gen Ryzen | Socket: AM4 | Size: ATX | Memory support: 4x DIMM, up to 128GB, up to DDR4-4733 (OC) | Expansion slots: 1x PCIe 3.0 x16, 1x PCIe x16 (x2), 3x PCIe 3.0 x1 | Video ports: 1x HDMI 2.1, 1x DVI-D | Storage: 1x M.2, 4x SATA 6Gbps | Networking: Realtek GbE LAN | Rear USB: 1x USB 3.2 Gen2, 3x USB 3.2 Gen1, 4x USB 2.0

Awesome value
Decent VRM and heatsink
Guaranteed next gen Ryzen support

AMD's A520 motherboard chipset might not make for the sexiest of PC components, that’s for sure. You probably wouldn’t buy one to take a place at the heart of your water cooled build or Nvidia RTX 3090 gaming system. When you look at the chipset itself, it doesn’t really miss out in terms of real world essential features. There’s no PCIe 4.0, but then no Intel systems have it either, not until Rocket Lake next year.

The Gigabyte A520 Aorus Elite is a high-end A520 board, which might seem oxymoronic, but if you didn’t know what it was you’d be forgiven for assuming it was more of a mid-range board and not a $90 bargain. It’s even got two RGB headers and a further two ARGB headers. About the only thing it really lacks is Wi-Fi, but then do you really expect to have Wi-Fi at this price? 

Gigabyte deserves credit for including audio built around the ALC1200 codec. Usually this is reserved for use with more expensive motherboards. If you’re on a budget, this Gigabyte A520 Aorus Elite is well worth a look. It leaves Intel's budget B460 boards looking weak in comparison, plus you get the benefit of next generation Ryzen compatibility. Is it for everyone? No, but the Gigabyte A520 Aorus Elite, unlike almost all preceding A320 boards, definitely does not mean cheap and nasty.

Jargon buster - motherboard terminology

ATX, Micro-ATX, Mini-ITX

The most common form factors/sizes of a motherboard from largest to smallest, which beyond physical dimensions determines which cases it'll fit into and (broadly) how many expansion slots are available. There are other, less common form factors as well (XL-ATX, HPTX, etc.) but these three are the most ubiquitous consumer form factors.

USB Header

A connector on the motherboard that allows you to run a cable to the case to add additional USB ports, typically on the front panel (though some cases provide top or rear panel slots as well). 

BIOS/UEFI

Basic Input/Output System/Unified Extensible Firmware Interface, which connects the hardware and software that lives on the board (the firmware) to the operating system (OS, such as Windows or Linux). They allow you to adjust system level settings, such as fan speed or RAM frequency. UEFI has largely replaced the older BIOS standard.

Expansion Slots (PCIe Slots)

Peripheral Component Interconnect Express slots on the motherboard are designed to accommodate add-in cards like graphics cards, SSD cards, dedicated sound cards, etc. PCIe slots are measured in both length (x16, x8, x4, x1) as well as by the number of data transmission lanes they provide (x16, x8, x4, x1). It's possible for a x16 slot to only provide 8 lanes of data, for instance, which means the maximum possible data transfer rate is halved (though in many cases, because PCIe provides such a high ceiling for transfer speeds, a lower number of lanes doesn't make a tremendous difference).

DIMM Slots

Dual In-Line Memory Module slots, the slots on a motherboard where your RAM lives. The number of total slots contributes to the maximum amount of RAM your system can handle, paired with the chipset and OS. 

Chipset

The logic that allows the various parts of a motherboard to talk to each other. The chipset determines which processor generations a motherboard is compatible with, as well as what add-in cards can be used.

SATA Ports

Serial Advanced Technology Attachment ports, an interface for connecting storage devices/drives to a motherboard (HDDs, SSDs, optical drives, etc.). The number of physical ports on your board, combined with ports for NVMe storage, will determine the total number of storage drives you can have connected to your PC at any time.

Dave has been obsessed with gaming since the days of Zaxxon on the Colecovision, and code books for the Commodore Vic 20 (Death Race 2000!). He built his first gaming PC at the tender age of 16, and finally finished bug-fixing the Cyrix-based system around a year later. When he dropped it out of the window. Thankfully it's a lot easier to build a gaming rig now there are no motherboard jumper switches, though he has been breaking technology ever since… at least he gets paid for it now.
