When I was using the GTX 780 as a dedicated physx card, the memory would boost up to maximum speed, but the core clock never rose above ~983 MHz.
For the one physx game that has a benchmark, Metro: LL, the dedicated physx GTX 780 marginally raised my average minimum framerate and noticeably increased my maximum framerate. It did seem to reduce the framerate variation as well.
Running physx on my GTX 980Ti was really bad. Minimum framerates went down, maximum framerates went down and the framerate variation increased noticeably.
