Hi, new to parallels, getting it soon. Will be running SolidWorks on Windows 7 a 3D cad program. It only uses one cpu so I am good with that. My question is my video card has 1500 mb ram and I have 16 gb system ram. Parallels pro allows you to set up to 64 gb vram which I'm not too clear about. Do I set my vram according to the video ram that I have or the system ram? Would it benefit me to get parallels pro instead of the basic parallels? Thanks
