The nvidia 560 is way out of my price range (~$250!). I would rather stay below $100. I don't need to play new fancy games. All I play is UrbanTerror (ioquake3). This runs decently on my nvidia 9300m GS and an old Radeon 300. I would like to get a bit better performance than those old cards and I wanted to find something that was going to work well under linux.
