When Intel announced its 9th generation Core processors earlier this month, there was only one thought on everyone’s mind: will I need a new motherboard? That might be a bit of a generalization, but not a total stretch. The company's new Z390 chipset means a deluge of flashy new motherboards, which in turn means discounts on the older models—just in time for Cyber Monday. And let’s not forget that AMD released its 2nd gen Ryzen processors earlier this year, so expect to have your pick of the lot this holiday season.
If you're thinking about upgrading your motherboard, now is a great time to make the switch. For Intel systems, we recommend Z390 and Z370 motherboards as the best option, though there are also some B360 boards that would be fine if you're not buying an unlocked K-series CPU. For AMD, X470 boards are at the top of the list, with B450, X370, and B350 options also being viable. If you're planning on a high performance build, we should see motherboards that normally cost $200 going for $150 or less, and we'll be updating this page throughout the next week or two with the best deals we can find.
Something else to consider is that while Intel CPUs don't usually get discounted as much as AMD offerings, the same isn't true of motherboards. A good deal on an Intel motherboard could make up the difference in pricing between an AMD and Intel build. Of course AMD motherboards are also seeing some great deals as well.

What to expect from motherboard deals on Black Friday and Cyber Monday
The Z390 boards are already stocked at online-retailers. They're not a total overhaul of the Z370s, but they've added a few extra features—specifically native USB 3.1 Gen2 support and faster 802.11ac Wave2 wifi. Most Z370 boards also have updated BIOSes to accommodate the new 9th gen Cores. If you are thinking on splurging on one of Intel's new CPUs, but need a new motherboard to go with it, you don't need to rush to get the newest one. Expect to see some of the same discounts again as last year.
As for motherboards with AMD chipsets, there were a few deals last year on motherboards that supported both first gen and second gen Ryzen processors, like the ASUS ROG Strix X370-F, so it seems likely we'll see those deals again. We've seen a lot of great deals on AMD motherboards already.
Of course, if you aren't sure what to put on your shopping list when the time comes, you can always take a look at our recommendations for the best gaming motherboards.
