Shoot, I was afraid you all would say that... running 5 Rift windows, with one game window focused and task manager in the background the cpu cores were all pegged at 100%. I was hoping the graphics card would make a difference since that same situation was giving only 3-5 fps in the city, and maybe 18-20 fps in deserted parts of the world.

Sounds like I really need to put together an i7-920 box before springing for 3 more accounts. I would love to get a 2600k system, but I don't think that's in the budget i have for this.
