For two card to work fully independent, you have to turn off CrossfireX in your Catalyst Control Center (CCC).  Then you have to connect one monitor to each card (or @=1 or 2+2) and add the startup parameter to each client shortcut to designate which card the should be rendered on.

Then as a final act, make sure you move your client windows to the correct display. Correct being the display matched the card being rendered on.

You may need to turn vsync off as I needed to to have the maximum effect. Mine setup works on windows 7, and also uses dual ATI cards. Your setup doesn't seem to be too different from mine, so should work just the same.

PS.

You can leave the CrosFire bridge between your cards connected, just disable crossfire in the CCC and reboot, thats all the hard work really.

Wonderful, all my 4 clients now are a tad above 30 FPS, which I am quite happy with. Both cards are at approximately 80% load now (I also enabled decorative plants and maxed the AF and Terain detail, I already had maximum draw distance).

I needed to turn off vsync to reach this FPS level however, which might indicate FPS is quite variable, with a lot of half rendered frames being tossed away when vsync is on.

Overall, I am very pleased....could not have asked for a better birthday present smile
