Hello Guys maybe you can help me with this issue
i have already tried the fix by EVIL-Furby in this post from another topic
http://forums.steampowered.com/forums/archive/index.php/t-1496253.html

whenever i am trying to play games via crossfire it seems to have issues where it disables the monitors then re-enables them again constantly
the issue only happens when crossfired but when i don't have crossfire enabled then the game runs fine but is too slow for the resolution

i have formatted the pc installed the latest drivers and also the beta drivers but this issue still isn't fixed

i can take a video and upload it if required to show more details but it seems rather annoying and im only gaming on 1 monitor so it isn't the issue with eyefinity

i have also removed the GPU's and re-inserted them again and issue still happens

details of rig below

MB ASUS Sabertooth 990FX
CPU AMD FX-8150 OC to 4.2Ghz (Watercooled Corsair H80)
RAM GSkill 16GB Ripjaw-Z 4GBx4
HDD 2TB Seagate
GPU 2X ASUS 7770 DirectCU 2GB
PSU 750W
Audio Soundblaster Recon 3D
Monitor is Acer S220HQL X2
OS Win 8 Enterprise


EDIT: the issue only seems to happen on some games not all
Call Of Duty seems to be the only issue i seem to be having at the moment
Need for Speed works fine

i have used both 13.4 and 13.6 BETA drivers and this is still the issue and have tried using a different PSU too but with same results

they was bought as 2X 4GB packs so 2X 2X4GB and i have checked all the numbers they are not the same batch as i got them a week apart from each other but all the timings are exactly the same and the DRAM voltage is set to AUTO with the sabertooth bios
