Is it possible to have my GTX 780 in my computer, and then have my 560ti below that and use it just for rendering with it in Sony Vegas??? My displays would be going through my 780 obviously if that matters at all.

Yes you can. Turn off SLI function. Go to Sony Vegas and select your second GPU as main Cuda render device. Then go to NVidia panel control and select your first GPU as the main source for media activities such as Gaming, etc. When you're gaming, you will see that there's less MB being used on the second GPU and that's because it's doing nothing. As where when you're rendering and gaming you will see different usages in both of the video cards and thats because they're processing different stuff. Then again, SLI mode puts the same usage on both video cards since both have to render the image presented on the game. You will pretty much notice what those cards are doing.

The only benefit of having the 560ti installed, would be to offload Physics rendering, but the 780 is more than capable of doing that quicker and displaying any images, so short answer, no, sell it and buy some extra RAM that SV will benefit more from.

No, it will not benefits anything. You can do PhysX calculation with gtx 560ti but a single 780 can handle both image rendering and PhysX calculation faster than your 560ti does. If you connect it to your MOBO, it will take power from your PSU and decrease 780's performance.

It all depends on the Codec of your render. GeForce based chips are mostly compatible with MP4 and so since they carry the H.264 and that's pretty much relevant to MP4 files. So try to render on MP4 concepts. Then again, you will be allowed to use CUDA as a render source. Keep in mind, CUDA would help your CPU by a lot! Less stress and mostly a faster render than just using your CPU.
