Of course it will work as a physx card. But normally, a 560Ti would just be a waste of money as a physx card..
Thanks guys. Well currently im semi happy with the performance of my 560ti (battlefield 3 is only on high). Still saving up and when I upgrade later on and new GPUs are out with so much performance boost with a better price then I may get one and just use my current 560ti as a PhysX but my original idea is still to do a SLI on it giving the setup quite a boost to over a 580 (plus I have overclocked mine to over 1000Mhz level)
