Design and Modelling
Selecting the number of processing cores in your SolidWorks workstation is critical. SolidWorks is a frequenc bound application so predominatley only uses one core. The frequency of that core will determine performance so a workstation with less cores at a higher frequency will be ideal.

Rendering and Simulation
Unlike 3D modelling and animation, rendering within maya is a multi-threaded process. Within SolidWorks, performace gains level off after 10 cores making an overclocked 8 or 10 core APEXX workstation perfect. If you are using Solidworks Visualize, which uses GPU rendering, then a multi-GPU solution would work well. If implementing CPU based programs such as Keyshot, then you may want to opt for a dual Xeon workstation.
