I actually just did a workstation build for my school and have another coming. A decent xeon, reliable psu/motherboard, good cooler, quadro k2000, enetrprise grade hdd (4tb+) with a decent size boot ssd should be very good. I would get a xeon. We use both firepros and quadros at school for cad, and autodesk inventor byfar takes advantage of the quadros features.
Yeah, I also have a Xeon and Quadro 2000 in my workstation. Adding 16gb of memory, a 120-250gb ssd, a 2tb hdd and a psu gold from Corsair, or Seasonic.
The CPU + Mobo I have to look at, but I do have a general idea. His programs are CAD related (Mastercam and solidworks)
