I've not tried this exactly, but I have experimented with image processing on a GPU. On the card I used at least, the main memory -> card memory bandwidth was the bottleneck. You really had to do quite a lot of processing on the GPU (much more than just a texture lookup) before you saw any speed increase. This was a few years ago, maybe more modern cards have enough bandwidth that you would see a speedup vs. the CPU.
