First let me say that I have never built up or selected a workstation for CAD purposes and know little about PC in general, just enough to be dangerous. I plan on upgrading to Solidworks 2020 and need to spec out a Dell workstation capable of handling this plus Simulation standard edition for the next foreseeable 4 years if possible. The assemblies I normally work with rarely exceed 1000 unique part files and on average the normal assemblies I work with are about 250 unique parts in size. I just purchased Simulation Standard edition and will be starting to learn how to use this so I just want to make sure my new workstation can handle my normal workload and some occasional sim work. If possible I would like to stay under $3500. Any advice and suggestions would be greatly appreciated.
