Using two GPU's

[Hunden]

Hi everyone, I am fairly new to computer gaming of any sort. I am currently using 2 ATI 5770 cards but not in crossfire with 3 monitors. I have my center monitor on one card and my 2 outer monitors on the other card. I am not using eyefinity due to the lack of a displayport adapter that i still need to purchase. IL2 operates using 3 monitors but it just seems like I'm not getting full use out of both of my cards. Being new to computers, I don't know if I'm missing something. It just seems like my cards are operating in series rather then parallel.The only reason I say this, is I will open ati overdrive for both cards on a forth monitor to see activity. One card will max out at 100% before the 2nd card starts to show activity.Also do I need to change something in the config ini to account for 2 gpu's. Any help would be welcome.
