I wonder if the success AMD is having right now in the CPU space can in the future extend to the GPU space. It would be awesome. I also wonder if in this case it is an issue of hardware or only something related to the drivers/API. Can they make something similar/backwards-compatible with Cuda but cheaper/better?
