Actually, since moving data to GPU memory and back is so costly, GPGPU is quite limited. For example, that's why you don't see it used for databases out of some paper or some NVidia marketing thing. A few years ago there were plans to integrate the GPU and CPU by AMD with a local fast interconect. But I don't know what happened with all that.
