I have heard that PhysX 3.0 SDK (currently they are on 2.8.4) will thread across multiple GPU's, so surely this means it requires CUDA 4? based driver

Or is this entirely independent and I have got confused over how nVidia implement PhysX relating to their CUDA. Either way surely it is a sign of things to come? (even if we are just talking in the folding and transcoding/encoding department).
Yes, PhysX is somewhat CUDA related, although not absolute mandatory, ie. the original AGEIA accelerator.

And PhysX 3.0 is supposed to thread across multiple CPU cores, not GPU's, that's what you mean? http://physxinfo.com/news/3414/physx...lti-threading/ No point in dividing it across multiple GPUs when something like a 9600 is enough to run it, at least in current implementations of it.
