I've never really been overfond of Windows, and I've become progressively less fond of the latest couple of iterations of both it and OSX to the point that I would prefer to avoid using either in the future if they both continue down the same developmental track they seem to be on, so I have lately been returning to my old goal of managing to make a Linux gaming computer. In the past, the thing that always held me back was that not enough games would run on it (and more specifically, not the ones that I wanted to), but it looks like it's more common now for games to come out with a Linux version -- at least, for Ubuntu -- and also that most things can be run with Wine these days. I've heard that Steam works reasonably well for some Linux distributions as well, which should help.

I'm planning on putting together an experimental PC soon in order to test my theory that the time may be right, but I'm wondering whether anybody here uses a Linux machine as a gaming computer, and what issues you may have run into if you do. Or advice you might have, games you have or haven't much luck running, all that sort of thing.
