That is a very good question, and one I am puzzled about as well.

If PhysX card + 8800 Ultra is slower than just using a single Ultra, then the answer is a clear one.

But with no support for G80, yet, AFAIK, then comparisons can't really be made. I am an Ultra user as well with a dedicated PhysX card. I am really puzzled if I'll loose SLI benefits, if I dedicated a single one for PhysX, and how it all would compare to Ultra SLI + PhysX, or using one as GPU and one as PhysX.

If there is a driver for G80 PhysX that worked now, for Vista Ultimate x64, then I would install the OS and do the benchmarks myself. Unfortunately, that doesn't appear to be possible
