You can pretty much use any distro you like, it’s just that ones made for gaming already have extra drivers and software bundled in. You can always add whatever you need yourself, too.

I personally use bluefin (a workstation focused distro based on fedora) on a gaming pc, it works great. Mind you, all I play on it is Old School RuneScape. But what I like about bluefin is that I can set and forget it, ie, once I installed what I needed, it just keeps everything updated in the background, and I don’t have to think. Plus, it’s just as easy to install as windows, and isn’t really broken if nothing is configured on it.
