well, if all you play is quake 2, then most cards will do just fine. voodoo3, tnt2 ultra, g400max just to name a few. or, you could spend a little more and get a radeon LE. then you can play quake 2 at 1280*1024 with anisotropic filtering and FSAA, yummy! Anythin after the radeon LE would most likely not be a budget option
