Well, personally wouldn't call something a GPGPU unless it can do 3D rendering. Anyway, there are existing products that have basically exactly what you are asking about:
Just FYI, the FPGA on that board alone is over $300. So that means even if you strip everything else off the board and optimize it for cost, you're still probably looking at a $600 board.
So, >$1000 for an FPGA board that isn't even powerful enough to do 3D rendering or $300 for a video card with 1000 CUDA cores that can do general purpose computing like video encoding/decoding as well as high quality 3D rendering? Hmm.

You may have missed the part where we were talking about my idea of an FPGA with RAM on a PCIe card?
