Sorry its the first thing that popped into my head.....
I maxed Borderlands 2 on my 560 Ti just slightly overclocked, it would run I think between 30-50 fps. Been a while can't remember.
Honestly I never understood the reasoning behind having a dedicated physx card anyway unless you just wanna have all the eye candy. Tho I have only a few games that actually use physx they have run without problems.
