We are looking to upgrade our computers but I woul like to know which is more important for running SW fast. We do not do any simulation or rendering. All I am concerned with is working within SolidWorks creating assemblies with about 50 parts. We are more concerned with updating parts and assemblies quickly. I am looking at getting a computer with about 16G of memory and upgrading the video card or leave the video card and go to 64G memory.
