Adding to what simias said, even an FPGA with built-in floating-point primitives can beat a GPU (in floating-point-heavy computations when the measure is performance/cost) only if the algorithm doesn't fit well onto the GPU architecture – for example, if you can make use of the highly flexible SRAM banks on the FPGA. I suppose there exist such workloads, but they're rare.
Also, keep in mind that no FPGA comes even close to the raw external memory bandwidth of modern GPUs.
