MintLinux and Pop!OS are normally the two front-runners for new users. Basically, if you use Steam and you don’t play online-only games with bad implementations of anti-cheat software, you are good to game on either.
Make a USB that you can “live boot” from, so you can test out how they work with your hardware before you actually install the OS. Generally speaking, Mint works better with AMD, and Pop! works better with Nvidia.
