Can second this comment regarding Linux Mint. Many years ago I tried switching to Linux (Ubuntu, I think, back around 2008) but I lacked the knowledge and skills to make it work. Three or four months ago I decided to try again and downloaded Mint and installed it. I've been reading that gaming on Linux had gotten worlds better lately.

I decided to just dip my toes first and set it up to dual boot, in case I chose to go back to Windows. I had very few problems with the installation and operation. Nothing that took more than a quick google search to solve. Since then it's been not unlike using Windows.

And yes, gaming seems to work pretty flawlessly too. I installed Steam and have had few issues with running any of the games I've tried.
