It's common knowledge that here at Solid Solutions we promote the use of DELL as our recomended hardware provider. We use Dell Precision Laptops for our Application Engineers and Satalite Training Venues while Desktops in our main offices Training suites. The Dell Precision range is a specifcilly design CAD Workstation grade piece of Hardware so you know you'll be able to get the most out of SOLIDWORKS.
Dell have released a utility called the "Dell Precision Performance Optimizer" and this contains pre-defined profiles for specific Software, one of which is Dassault Systèmes SOLIDWORKS. This applicaiton is provided to improve performance, by changing various system settings. This focuses on enabling multiple cpu cores, allowing multiple threads. Graphics are adjusted through vertical synhronization to adjust the refesh rate while system power schemes target higher performance and battery life while you're using SOLIDWORKS.
