Heyyo,
Linux does rock, I use Fedora Core 3 myslef.. but my ATI card sucks with it.. can't even run that penguin game.. and can barely run CS with winex.. maybe I really need to get cedega? but I'm too cheap to crank out the cash, lol.
I did see a version of linux that was made to literally be a windows 2000 emulator. It can use win 2k/xp drivers, and games run pretty decent! I forget the name of it though...
