So yes, 24 Pipes should own sli quite easily...except when high resolution FSAA comes into play, that's when the 24 pipes will not be able to keep up with 2x X850XTPE/6800Ultra in performance.

Two 6800GTs at 400 are basically two 6800 Ultras, minus the memory speed. Maybe I was mistaken but two 6800 Ultras in SLI at stock speeds don't quite make it to 10k. link here But honestly I wouldn't compare the clockspeeds of a NV40 series card to something from ATI, because the NV40 series does not rely on fillrate performance. They are two completely different architectures (at least compared to the current ATI cards), and 400MHz on an ATI card means a lot less than 400 on an NVIDIA NV40-based card.
