P.S. The computer is not being pushed to the limit and is only working about at 60% "power".
It's being taxed more than you know. The video options for this system is either Integrated Intel graphics, or Integrated Quatro 3100... neither of which works especially well for gaming graphics. While the CPU may only be taxed at 60%, its cycles are being robbed to support the video.
In any case, I'm glad you're working now.
