This desktop GPU will be very similar to the one they've designed for the PS3, dubbed the RSX or Reality Synthesizer, which has been said to be more powerful than two combined GeForce 6800 Ultras. The RSX has a 550MHz core clock and 300 million transistors, but both Sony and nVidia have been mum on other features.

Update: Some pictures of the new card have shown up at Tom's Hardware and AnandTech. Tom's is calling it the GeForce 7800 GTX.
