Sure hope you'll have more luck than I did with gaming under Linux.
I tried to set up Quake 3 Arena a while ago and it runs perfect (even more frames than in Windoze) except for the fact that I can't get the sound running at all.
After digging and asking around it's probably due to my soundcard not being worthy of ID Software's games, at least in Linux.
I didn't try to setup any more games (primary reason being that most other games I play don't have a Linux port), if you find out that Wine (or WineX) is good enough I might give that a try 'cause I'm pretty bored of having to reboot in Win all the time when I wanna play.
If I remember correctly from another thread on these forums WineX isn't exactly up to speed yet to emulate all Windoze games :/
