The CUDA Toolkit and SDK 2.3 betas are now available to registered developers. They include the following features:

  • GPUs in an SLI group are now enumerated individually, so you can achieve multi-GPU performance even when SLI is enabled for graphics.

Any more details on this point? Does it mean they can make Physx work on aux core of a 2nd dual GPU card?

No, this is just a CUDA feature - it means that CUDA can see the individual GPUs of a card in SLI mode. I don’t think PhysX has been changed to take advantage of this yet, but it may do in the future.
