The HD 5870 GPU has very good DP performance. Auto-tuned DGEMM reaches about 65% device utilization in my experience. This agrees with benchmarks done by Dongarra's group, I believe.
AMD hardware is powerful. But the software stack is relatively behind in supporting it. However, I don't think this is the dominating cost of adoption.
If you come from the nVidia world, kernels for AMD look completely different. I don't have enough experience to say it is harder in the AMD world compared with nVidia. I can say it is very different. That adds costs when there is a deep investment in CUDA.
