PS a few weeks ago - thread was called: "cuda performance advice"
See here relevant answers from Ross Walker & Scott Le Grand:
To add some info.
CUDA 6.5 is supported as of last week for AMBER 14 - see update.6
The 5% perf regression over cuda 5.0 still exists in 6.5 though so 5.0 is
still the recommended version. I believe a fix for the perf regression is
planned for cuda 7.0.
All the best
Ross
