the MPower board is for hardcore overclockers, so you don't need that. I don't think you need that much ram, but I'm not so sure if that would affect the virtual pc's if you lower the ram to 16gb or something.
Also, COD and Battlefield aren't that hard to run, and the fact that you only have HDMI Monitors leads me to assume the graphics won't mean so much to you. Hope this helps!
