What will a dedicated Physx do?

[Hampton]

I am running my 9800gt as primary display and the 8500 as dedicated physx.
What benefit will I see running my 8500gt as a dedicated Physx card?

You'll see a nice performance boost in games that support Physx, such as Mirror's Edge.

It will allow the 9800GT to render graphics only, and the 8500GT will render physics only.

It set its self up automatically in Vista but not sure about Win7

It may not work in Win7 yet. It is a Beta and that part of the drivers might not be functional.
