This is probably the thousandth or so time ive posted this. Wait till the actaul cards are released, why spread more confusion and end up looking like an *** if the side you so strongly threw forward as fact comes up very short of what actually occurs. They dont show any system specs excluding the video cards, I wont believe it for a second at this point.
I do beleive it will outperform the GTX, but im skeptical at what ATI is saying about it. They did the same thing with the 6800 ultra and the x800, claiming that the x800 was 40% faster in the majority of games tested, this obviosly came to be false, the only card even come close to that margin was the x850xt, which was released some 4 or 5 months after the said statement, and it was still nowhere near 40% gain.
If the x1800xt lives up to these paper releases, as a lot of you seam to be so in love with, then you will see a 7800GTX in the classifieds shortly.
