I must admit nvidia has been shocked by ATI come back, like a i said in a previous post ATI has brought out one good card, then the follow ups not as good, then 1 good and then so on. So weather they will keep the market for these high end cards i do not know. But as you can see the nvidia sales are dropping, which i feel maybe because of the economy break down that people can not afford the expensive cards, or just ATI doing better. One thing most important about the lower end ATI cards is they have no Phycs capability like the 8800gt.
Other wise i am really happy to see ATI in this maybe its going to get the ball rolling, and hopefully lower the prices of nvidia cards.
