Nvidia makes a fine GPU. The problem with Nvidia on linux is the drivers. You're beholden to Team Green for driver updates, and when they decide not to support a GPU anymore, that's it. Now, linux does have the nouveau driver, but that doesn't support all the hardware or much 3d at all, and never will.

I particularly got fed up with Nvidia on linux playing War Thunder - I had a regular crash that Gaijin and Nvidia each blamed on each other, and I never did get it fixed.

Nvidia driver updates can also leave you stuck with no desktop environment on occasion and while fixable, it's a pain in the rear. However, when the drivers are right, Nvidia performance is second to none.

AMD has drivers built right into the kernel, and as long as you have whichever nonfree firmware repos your distro supports (I use Devuan, a Debian derivative), AMD cards 'just work'. If using xorg, install xserver-xorg-video-amdgpu for modern cards, and xserver-xorg-video-radeon for older cards. I'm currently playing on a Radeon 9070 (non-XT) on a 1440p monitor with plenty of performance. I know that it also works on wayland, but I have no experience there.
