I went with the review that this site had on the nvidia 7600 and the ati x1650 pro with 512mg. ATI got the good review and I went with it. The card is amazing as far as refresh rates and graphics. But stability is another issue. Some times I can play heavy graphic games for hours and it will lock up, and sometimes within minutes. I go to my game video options and let it auto calculate or go look at the card to see what it can do and if i try the game it is real unstable. I used to have a nvidia 5500 215meg card and it was very stable and overclocked! Just looking to see what drivers, control software I can use. I just don't want to have to use a $170 card that is no better than the one I had before.
