One of the problems for AMD is that everybody uses nVidia for computing, and nobody uses AMD. One of the reasons is thaf they have been ignoring non-mainstream GPU market. Well, those non-mainstream markets become mainstream and if you fall behind it is almost impossible to catch up. I personally prefer AMD's GPUs for computing and prefer OpenCL to CUDA. But, they are minor, since nvidia has much better software offering. AMD absolutely need to offer superb Linux story if they want to get people to use their hardware for computing instead of nvidia. They need Linux more than Linux needs them.
