Basically this is a video quality test, not a performance or FPS test. In theory, there should be no real difference in image quality between the two nVidia boards (6800/7800) except, of course, in the frame rates and added pipes.

ATI used to pay a performance penalty because they did once upon a time have an image quality edge that cost in GPU cycles (about two-three years ago). Then they even gained a performance edge (9800 series stuff) until about when the nVidia 6800 series and it's off-spring hit the street. To me the difference back then was very perceptible- but it seems to be a tie right now.

I don't have an 1800, so this update could well be lost on me. 5.13 may just be an unlucky number except for maybe some fixes and trinkets. But this would have to be a WOW release to top what's currently out there and I can't really discern a lot from the article's pictures.

The truth remains to be seen ....
