Yes, it does.
Do you have the cuda libraries for the 319 version installed?
Yes
I don't play around with GPU computations, but from what I have read it
does need a certain size job before the overhead of transfering the
data and managing the GPU makse it worthwhile, but for large jobs the
high core count and memory bandwidth makes a big difference.
500,000 atoms, as in my test, is a large system for unbiased molecular dynamics. At any event, I looked at the the nvidia-cuda-toolkit version 5.0. nvidia for GPU Computing SDK, to build examples that should include a bandwidth test, offers linux packages for Fedora RHEL Ubuntu OpenSUSE and SUSE. No Debian. I had unpleasant experiences with Ubuntu packages, and it is well known that Ubuntu, unlike LinuxMint, is not compatible with Debian. Therefore, I did not try the cuda toolkit. I wonder why Ubuntu has so widely replaced Debian among the mass. Sad, and somewhat irritating, for me.
I tried

francesco@gig64:~/tmp$ ./CUDA-Z-0.7.189.run

Actually the required lib is available, as shown by my copy into tmp. I don't remember the source of this GNU CUDA-Z tool. Any experience with?
I have also met reports of unexciting experience with PCIe 3.0, that is meager or no gain over PCIe 2.0, however it deals of people carrying out games, which is different from NAMD molecular dynamics, where most is done by the GPUs but AT EACH STEP energy has to be calculated by the CPU.
