I'd just go AMD. The drivers there are much more mature due to Google and Valve contributions, and the performance of an 9070 XT is great while being cheaper than the equivalent 5070 Ti. FSR4 is a solid competitor to DLSS and works in any game that supports FSR 3.1.

Anti-cheats won't work, I keep a Windows drive just for Battlefield 6.

I got fed up about a week ago and ditched my Nvidia GPU for a 9070XT.

I run CachyOS and have been having a nightmare of a time on Wayland with my 3D Printer slicer and other tools I use my computer for being unusable.

The only thing that has ever kept me on Nvidia all these years is that they have been killing AMD performance wise for gaming.

The 9070XT is easily performant enough for the gaming I'm doing at the moment, and I can finally ditch the last major headache I've had in two and a half decades of being a Linux user - NVIDIA drivers - good riddance.

I don't play online games other than Helldivers 2 (so anti-cheat is a non-issue) which is working just fine at 70-80FPS max settings in 4K. Also getting good performance with RT off playing Ghostwire in 4K with settings as high as I can get them while staying above 60 FPS with Freesync.

EDIT: 9070XT seems to have a bit of headroom too I got the Asus PRIME OC version; Using LACT I upped the power limit from the stock 317W to 340W and undervolted by -100mv (YMMV on this value) and can get a decent chunk of extra performance out of it.
