I have used it with, I think it was 512x521, images with 60 FPS. So for your case it should be enough. If CUDA doesn't fit well your needs, then you can take a look into just GPGPU FFT algorithms. I have seen on the nVidia's webpage an OpenGL shader based application which can do compute FFT on the GPU. Even more I could try to manage to create something for osgPPU, then you could use from there, if you like.
