Have you turned off the max fps cap?

Type in console /com_maxfps (desired fps)

Yes, one of the first things I Did. I soon found out that its because my PCI-E is 16/8 so when two cards are in play, they are at 8/8 so its like im running old PCI-E's. I used the overdrive utility and got much better results.

I am now running at a respectful 100+fps, and cap out at times around 205fps.

I don't think it is bandwith issues. Pci-e barey uses what is has capability to. I might just be that the game dosnt like crossfire...
