Workstations are imho not best if you plan to do long-taking simulations. Only 
think about this option if you're doing really short (minutes ~ hours)

RAM size shouldn't be an issue, except if you're simulating huge systems. 

I am not up-to-date how the "new" intel core architecture performs compared to 
AMD opterons but opterons probably give you the biggest "bang for the buck".
Maybe someone can provide up-to date information, the Gromacs benchmarks 
aren't informative about this.

Well depending on the available infrastructure, a "cheap" workstation for 800€ 
will do the job. Then you have 4200€ remaining to buy compute bricks. You 
should definitely get more than 4 cores from this ammount.

Yepp, plz comment my comments, since we're planing to by additional compute 
ATM, we're thinking about 8-way opteron nodes with barcelona core, if it is
