Amazon AU is running a big gaming sale at the moment

Razer Blade Stealth 13 | i7-1065G7 | 16GB RAM | 512GB SSD | GTX 1650 | AU$2,789.10 (RRP AU$3,749)
If you're after a sleek work laptop that can also play games, this is a must-investigate. The 1080p monitor boasts a 120Hz refresh rate, and while the specs won't have you running modern games on ultra, you shouldn't have much trouble playing most things. 

HP Omen 17 | i9-9880H | 32GB RAM  512GB SSD | RTX 2080 | AU$3,137.20 (RRP AU$3,669.25)

RTX equipped gaming laptops are always going to break the bank, but over AU$500 off this 17 inch, 1080p lappie (see specs above) might be worth investigation. There's only one left in stock, though: be quick.

ASUS ROG G512 | i7-10750H | 16GB RAM | 512GB SSD | RTX 2070 | AU$2,099 (usually around AU$2,500)
Very nice specs at this price, with a 1080p screen with 144Hz refresh rate. Also boasts pretty flashing colours, which is always appreciated. 

Razer DeathAdder V2 | AU$99 (RRP AU$139.95)

The Razer DeathAdder V2 got a rave when we reviewed it in March. The wired mouse is definitely on the pricey side, but maybe it'll be worth your while with AU$40.95 taken off the RRP.

Razer BlackWidow Chroma | AU$139.10 (RRP AU$219.95)
A nice AU$80 bucks off this green switch mechanical gaming keyboard, which is, of course, adorned with enough colourful illumination to light a disco.

Razer Kraken Tournament Edition | AU$99 (RRP: AU$169.95)
Just over AU$70 off this plush gaming headset with external audio controls unit. It boasts THX spatial audio, 50mm drivers and a convenient way to control the game / chat balance.
