Looking at buying a Dell Workstation to be use for design work using SolidWorks 3D software suite. Have choice of single Intel® Xeon® Processor E5-1650 (Six Core 3.2GHz, 12M, Turbo+) or Dual (2) Intel Xeon X5550 Quad-Core 2.66GHz 8MB CPUs. Looking at running Windows 7 Professional with 32 gb ram and 4GB graphics card. Can someone explain the advantage (if any) of going with the dual processor machine vs the single processor machine? Both configurations are about the same price but just didn't know if 2 processors would be and advantage in this application.
