IL2 1946 Triple Head FPS

Yep, that makes sense now.

You need to have ALL monitors plugged into your primary video card, at least from an ATI perspective. Eyefinity requires this. I would assume Nvidia is the same based on what you're saying.

You'll need to get an HDMI or Displayport adapter or something like that to ensure that all of your monitors can be plugged into the 480gtx. I'd get rid of that 8400, it's not benefiting you in any way, even for physx.
