Thank you for clearing that up for me DarthShader
Although I am sure I did hear somewhere that PhysX 3.0 would be kinder in multiGPU situations. At the moment on the single PCB GTX 295 all PhysX processing is done on GPU B

Rendering is done on both GPU A+B. So in games which use PhysX GPU B is working a lot harder than GPU A. If the work could be split across multiple GPU's, then PhysX would have less of an impact.

But hey, nothing wrong with having some SSE and multi-threading love
