Please have a look at the gmx-users history, there has been recent
discussions about this topic.
* If you only/mostly run GROMACS using GPU, Intel CPUs with many fast cores
combined with high-end Geforce GTX cards will give the best performance/$;
e.g. currently i7 4930K + GTX 770,780 is what I would recommend
* The ideal hardware balance depends on the kind of simulations you plan to
do (e.g. system size, cut-off, #of concurrent simulations, etc.).
Note however, that you could get much better perf/buck on e.g. AMD CPUs
with middle-range GTX cards e.g. if you have many small simulations to run
concurrently (and especially if you want rack-mountable OEM servers).
