I still see people asking which distro to use, is it ok if they have an Nvidia card? How ready is Linux for a gamer? I have been 8 months now on Linux, it's about this hard to have an Nvidia card: click update. The way I switched was to populate the second m.2 slot on my MB and install Linux there, I chose Nobara, that way I had the fallback of Windows 10 if I had issues. Well, I still have Windows 10, it exists as a console with no internet access, it runs my Skyrim setup with it's 982 mods that I can't be arsed to move. Everything else is on Linux, it's the default and daily driver. Look close, you can see my system automatically updating OpenMW for me, quietly supporting my 260+ mod remaster of Morrowind. If you're wondering whether Linux is ready for gaming, yea, it is. Give it a try.
My 5000 series has worked out of the box on Bazzite. The only GPU bug I've run into is that Moonlight is incompatible with the driver. All of the games I've tried have worked with proton GE, and with some config tinkering I even have VR with full body tracking working for VRChat....
HOWEVER
I can't say its a premium experience for competitive games or VR. Both have latency issues that impact the experience. Maybe an older shooter like openMW would be just fine, but modern games like Rematch have had some weirdness, even though they "run fine".
