this has nothing to do with NAMD. if you can stick in
the GPUs, you can use them with CUDA.
however, whether you'll get good performance
out of it is a different question. performance depends
not only on the capability of the GPU but also
on the available bandwidth on the PCIe slots
(are all of them *real* 16x PCIe 2.x?) and the
memory bandwidth available to the CPUs.
because of those issues, performance will also
depend on the size of the problem that you'll
be running. not easy to tell up front,
