I am testing various laptop configurations (Dell) and most of my test are based around the CPU, memory, and disk.  Opening, rebuilding, saving, creating a drawing with detail views, etc.  The (2) video cards I am testing are the M2000M and the M4000M.  NVidia recommends the M4000M for large assemblies, which we primarily have. We rarely do any rendering, so I am looking for some test that I can do to measure video card performance. Any suggestions?
