Wondering which ones you've had best luck with. I also have an asus 6800pure that more than doubles the ultra's score with similar cpu's in 3dmark2k. I use 3d mark to compare scores with different fsb's,cpu's or drivers to test effect.
550@794-P3 with the ultra(3D-2300) vs 533@896-C2 or 633@979-C2 with the 6800(4890-3D)--(the 2 C2's score the same with 3dmark2k as I swap out the cpu's only)
