"The GeForce 6800's was a bit less dominant over the Radeon 9800 XT using our custom demo in the Unreal Tournament 2004 benchmark. Without any anti-aliasing and with 4X AA enabled, the 6800 was somewhat faster then the 5950 Ultra and 9800 XT. When we enabled anti-aliasing an Anisotropic filtering, however, the Radeon 9800 XT was able to pull ahead of the 12-Pipe 6800 by 25% - 40%. The pricier X800 Pro and GeForce 6800 GT continue to be in a league of their own."
just read that, so im going to choose the x800pro over the 6800
