Lacking a strong scientific reason (e.g. continuity with previous work) 
you should not be planning to use a version that's 3 or 4 years old. 
GROMACS 4.x is much faster.

That said, pretty much anything will be reasonable, but don't skimp on 
your network. Even gigabit ethernet is not very useful. Search the 
archives for posts recommending Infiniband.
