780 GTX Main card and what could I use a PHYSX card? Currently Have 240GT.

Solution
The GT 240 is too slow to benefit a GTX 780. It WILL slow down your performance. At a minimum, you should be looking at a GTX 650. The keys are cards that have both high core clocks and a high CUDA core count, with the GTX 650 as your minimum yardstick.
This is from about the only set of benchmarks using recent video cards for dedicated PhysX, and a high-end primary graphics card.

As per Nvidia:
Which NVIDIA GeForce GPUs support PhysX?
The minimum requirement to support GPU-accelerated PhysX is a GeForce 8-series or later GPU with a minimum of 32 cores and a minimum of 256MB dedicated graphics memory. However, each PhysX application has its own GPU and memory recommendations. In general, 512MB of graphics memory is recommended unless you have a GPU that is dedicated to PhysX. - See more at: http://www.nvidia.com/object/physx_faq.html#q3
The 240GT: http://www.geforce.com/hardware/desktop-gpus/geforce-gt-240/specifications
So, it should work fine. But I doubt you'd need it. PhysX uses very little resources and the GTX 780 has plenty to spare.

Wait you are saying that using the GT 240 would actually result in worse benchmarks then not using it?
Any data on that?
The graphs you provided actually show benefit when PPU is coupled with the stand alone card. All the FPS beyond a non-PPU are higher.
