Radeon and GeForce Share Work, PhysX Applications Win
The functionality of CUDA and its implementation of GPU-accelerated PhysX processing has benefited many a GeForce user. Users of ATI accelerators lacking this incentive either use Ageia PhysX card or avoid it altogether. It has been verified by Hardspell that in an environment where Radeon accelerator(s) do graphics processing, a GeForce accelerator can be used standalone to process PhysX. Hardspell used a Radeon HD 3850 along with a GeForce 9600 GT on the same system with the display connected to the Radeon, though no form of multi-GPU graphics connection existed, the GeForce card partnered the Radeon well in processing physics, while the Radeon did graphics. Results of the oZone 3D FluidMark, a benchmark that includes routines to evaluate the machine's capability in processing physics, showed a greater than 350% increase in scores, showing that the GeForce accelerator is doing its job.This was further proved with game testing of Unreal Tournament III. Provided are screen-shots from the game along with those of the FluidMark windows. The first window shows a score of 759 o3marks, while the second window in which GeForce processed PhysX, the score jumped to 2909 o3marks.

Still begs the question whether or not it is needed. I have considered myself getting a cheap 8 series gfx card for physics, but so few games use them, it only seems to be benchmarks that truely benefit. :(
I've been waiting for this as I have mostly used ATI/AMD graphics, but pondered how to implement physics going forward. Can't wait to see how this unfolds.
hmm.
I think XP only supports 2 GPU's. Thats the main reason I went to Vista so I could run the 3 3870's together.

We are at Crossroads now . TO go with Xp and PhysX or Vista and xfire .
How many games will benefit from Xfire, vs PhysX...?
Thing is PhysX adds extra dimension to the game, while all xfire does is give you good framerates .
look at the videos here

XP supports at least 3 graphics cards.
Some people are on a budget and can't "just buy a 200 series card" lol.
