My rig has an 8800GTX as its main video card, however I also have an 8600GT in it as well driving extra monitors. Does anyone know if it is (or will be) possible to tell PhysX enabled games to utilize the 8600GT as a dedicated Physics engine? Or will it use the 8800GTX for both PhysX and graphics rendering? On a similar note, I know the 8600GT is not exactly a 1337 card, would it even have the horsepower to do PhysX calculations?
