The answer to this question is very system dependent, so my suggestion is
to run a benchmark simulation. If you're simulating a system in explicit
solvent, the performance will remain pretty much stable in time, so you can
run a very short simulation (i.e. 100ps) and check at the end of the log
file how many nanoseconds per day would you simulate with a given hardware
configuration. You might want to try many different hardware configurations
and see which one provides the highest ns/day ratio for your system.
