I was recently given a HP Z800 Workstation (see specs below) as a at home PC. For being a 6+ year old machine it runs fairly fast. The other 2 CAD/CAM software that I use on it have run well. However when I an in Solidworks (15 or 16) it is really slow and slow to to refresh. When I monitor the CPU and GPU loads nothing is even close to 100%. The parts I am working with are on the simple to medium size and features and the assemblies are in the same category, maybe 30 total components.
I believe the video card is a weaker point, and was thinking about upgrading that to a Quadro K1200.
Is the video card my issue and will the new Quadro card a good one to choose?
Are there any settings that would help with this refresh issue?
