I am currently using TechPowerUp GPU-Z 0.5.1 on a Windows 7 64-bit system. My system has dual NVIDIA GeForce GTS240 graphics cards in it. I have it set with SLI enabled. I have check marks for Computing, CUDA and DirectCompute 4.0 but I have no check mark for PhysX. There should be a check mark for PhysX for this card or am I wrong?
