If you want to test it a bit install Ubuntu and then try Steam out there.
Alright thanks. Do you know any programs to play windows games on linux?
WINE and PlayOnLinux. Wine runs many windows aps but not always with the best of results, playonlinux is a frontend to wine that will install many windows games and such. I am not a gamer so no critique from me on that point but you can go to winehq and see how well each game is rated for performance.
