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.
I have had quite a few nvidia cards in my linux systems and all ran fine, except for a while when Wayland came along. Those issues have now been fixed as well. Your experience may vary ofcourse depending on the hard and software you use. But there is no reason to not use Nvidia on Linux.
That being said, I switched to AMD recently and had some issues with suspend and resume so it is not like AMD is the holy grail for Linux systems. I made the switch because of the opensource drivers and Nvidia being greedy fucks.
