I'm really stumped, cause they both look like good cards, but the prices are all over the place. I look on pricewatch and the price for the ultimate is more then the price for the ATi radeon pro 256mb. I look on the ATI website and ATI 256mb pro is $500.00.the Ultimate is only $400.00 bucks. The statistics for each card seems the same, but I can't find a site or anything that compares the two. Can anyone give me some help I really need to get a card, that's all i need to finish my PC. Thanks.
