bimbang,
I am not aware of a site that has specific configuration reviews / recommendations for your exact example but I did find a few resources you might could start with that might get you closer to the answers you are seeking:
Arrival of the Desktop Supercomputer:

Advice and information for optimizing use of desktop and mobile workstations for CAD and related applications:

Sorry I couldn't find anything specific but maybe one of these resources will offer some help but I do find the Intel Nehalem generation super computer article interesting enough for more analysis (it says nothing of cost to that might negate any positives). In it the author states,"In one test I observed, a last-generation workstation could process one frame from one of these applications every 50 seconds. By comparison, a single Nehalem-generation workstation running virtualization software can process 30 frames per second in two applications, one in Windows and the other in Linux. That's roughly a 3,600% productivity gain".
Thanks
Jay
