Now get rid of those 2 video cards in there and get yourself a 4800+

Or a 5800+. Ati's naming is silly, but you can tell what "grade" of card you have the the 100's. If it's a 4100, it's a low end 4000. If its a 4400, it's a low end mid range. If it's a 4800+ its in the higher range. Same with all other models. 3000, 4000, 5000...
