This is a must read for everyone intending to play with PhysX. This will solve a lot of your questions and problems that you are going to have.
NVIDIA's GeForce PhysX implementation
NVIDIA has created three sets of circumstances on how you can choose to use your PhysX setup from within the PhysX driver, let's have a look:
Below is an example pic of
Most IMPORTANT
Now there's a thing you will need to be aware of in the Multi GPU mode, it's actually a Vista limitation but a second monitor must be attached to enable PhysX running on the second GeForce GPU. You must extend your Windows Vista desktop onto that monitor.
To bypass that issue, most monitors have a standard VGA and a DVI connector, right? Just use both. This limitation is related to the Windows Vista display driver model (WDDM). This limitation does not exist in Windows XP. In NVIDIA's upcoming drivers, they will be offering a workaround to improve the experience for Windows Vista users.
In other words you do not need to have 2 monitors in XP, while in Vista you need 2 connections or you can bypass that with above trick.
With a single card or two cards in SLI mode you will not have this problem.

- Standard - one GPU renders both Graphics + PhysX (not ideal as you'll need a lot of GPU horsepower).
- SLI mode - have two GPUs render both Graphics + PhysX (SLI motherboard required)
- Multi-GPU mode - GPU1 renders Graphics and GPU2 renders PhysX (SLI motherboard not required)
