Is there a dedicated graphics card in that PC?

Or is it just using the one that is on the motherboard?

If there is not a graphics card in it, are you able to borrow one to throw in that PC and test it?

Your CPU is better than the computer I am on now and I can run Rhino, MoI, Fusion 360, SpaceClaim, all without issues. Twelve years ago I ran SolidWorks on a laptop and imagine the specs of a laptop that long ago were like.
