Yes it would, we'll just have to wait and see though, would be hilarious though if there was already a faster card than the R600 out, ATi would be out of it before they even launched, what a ******.
Still their R600's are their 2nd Dx10 generation, and Nvidia have just launched their first, so it could be in Dx10 where ATi could do the better, its going to be very interesting indeed, and if thats the case ATi will not be out of it, they will be ahead as they will be the better option, around the same in Dx9, but better at Dx10, they would be the way to go as its upcoming Dx10 that matters now.
