Problem with my crossfire setup while playing games

First I would like to begin by showing you all what kind of components I use

Sapphire HD Radeon 6870 x2 (crossfire)
80gb SSD corsair
Corsair TX V2 650W PSU
Corsair Vengeance DDR3 1600MHz 8GB CL9
Cooler Master CM 690 II Advanced Svart
AMD Phenom II X4 965T Black Edition
Windows 7 home premium 64bit.

Well the problem is that my crossfire setup doesnt maximum its capacity while running games such as World of Warcraft and Battlefield 3. The GPU performs much as a single card so with other words I have more FPS with one card than with two. By the way I have also updated my catalyst control center and my other components are up-to-date

  1. "If a man speaks in the forest and no woman hears him, is he still wrong ?"

    try this:
    1-uninstall ccc and caps,shut down.
    2-remove second card,restart
    3-install latest ccc and caps,shut down.
    4-reinstall second card,start up.

    I did have that type of an issue on another build and this seemed to work.
  2. Ohh I have a MSi 870A-G54! :)
