I thought it was like telling you to eat cookies.
Or like telling you to lower your settings on Crysis if your framerate is choppy.
Basically you have 2 options, play games that are small enough to process at a rate that you are comfortable with, or multitask. My roommate runs a dual monitor setup and likes to play streaming video while he is gaming. For Dom3, I just play in windowed mode, and browse forums or surf while turns process.
