Does anyone have experience with CUDA AND FPGA? Some kind of benchmark FPGA vs. CUDA will be helpfull.
Well, a very important question would be, "Do the tools you want to use exist for FPGAs?"
FPGAs are typically much better in performance per watt right now, but a bit slower, more expensive, and a royal pain to program.
I currently have no plans to support FPGAs. Throw me ten thousand dollars and I might be motivated to update my tools for them, but right now, I have no plans to support them, and I don't believe many other tools have this support either.
So that would make the 470s a better option. Why not go with GTX580s, though? They perform significantly better.
