I switched to Linux full-time a couple years ago. I had a Windows desktop for the same reasons - games.

Once Valve incorporated Proton, it was all over for Windows for me. I already used Linux (Debian/Devuan) full-time at work on my laptops and servers.

I don't miss Windows at all. Running Devuan right now on an AMD B450 with a 5600, 64GB RAM, and a 1080ti.

I will admit that video driver updates are a little more involved than on Windows, but since I don't have a mainstream Linux distro like Ubuntu, that's to be expected.
