I have noticed lower FPS while running AMD CrossFireX after installing my second graphics card. I am running World of Warcraft averaging 40 FPS with CrossFireX and 50 without. While tabbing between the desktop and the game my screen will sometimes change the color of the window to its opposite for a second and then go to either the desktop or the game. WoW will turn blue, my Windows 7 blue desktop will turn orange. After reading some post I tried reinstalling the drivers and with the latest driver I began crashing on top of my problem of CrossFireX not working. I enabled the ingame icon to be sure that it was actually on which is was. I have some concern about my new motherboard that I just purchased. I did not realize that the PCI-E ports are x16 and x4. I have read numerous reviews about this subject being bad or being good. I really do not want to replace the motherboard but if I have to I will. I hope that one of you experts can help me out with my problem.

Update: After switching the graphics card slot I noticed the performance in the x4 slot was 1 FPS higher then the performance in the x16 slot. I was averaging 45 FPS in the x4, tested both card ports, and 44 FPS in the x16 slot on single mode on both cards. I tried CrossFireX on both slots averaging 44 FPS and was still getting the color problem while changing between windows.
I have been trying to switch around the cards and re install different drivers. I discovered that if I plug the DVI cable into the bottom or the top card during boot and enable CrossFireX the opposing card no longer works if I change the DVI cable to that card. I do not know if that is normal or not.
