I keep a Windows machine around purely for games, mostly Ubisoft, COD, and miscellaneous Steam titles. But that's it - everything else is on a remote Linux machine via putty, or in the browser. I have a Mac for the rest of my life. I'd be very happy moving the desktop to Linux, and I've dual-booted it before, but always come back to Windows to play games. What's the best current resource on gaming from Linux and how to convert?
