I'm running Linux for everything and my GTX 1070 is still chugging along trying to power my 1440p 144hz monitor ^^'

Well, I mostly just play strategy games and CS2 (which I do have to run on almost the lowest possible settings without FSR. I basically turn everything to lowest except for lowest still AA setting and dynamic shadows to not have a disadvantage and get 110 - 180 fps depending on the situation)

But I'm planning on buying a used Radeon 9070 XT and just inserting it into my current build (i7 6800k based lololol) and on eventually buying a new build around it

(A 750W 80 Plus Platinum PSU should be able to handle a new 970 XT)
