Doom 3 Benchmarks at VR-Zone
 

Although the 6800 trashes the X800XT-PE I like to see what the new ATI drivers can do

quote from the article:

"What we learned today was that NVIDIA's backing of Doom 3 is definitely not
unfounded. At press time we weren't able to get a working GeForce 6800 GT or Ultra
graphics card running on the AGP bus, but we'll be getting those in later this week.
Still, the standard GeForce 6800 was able to run Doom 3 almost as fast as the Radeon
X800 XT Platinum Edition, a card almost double its price"
