I am using eyefinity and i have already spent too much money on this setup.. And i am still lagging in eyefinity games!? :~
And i wonder if someone could help me find the problem of my system.. :(
The question is: What makes eyefinity supported games lagg?

The system:

Win 7 | 64-bit
graphics cards: 2x= (xfx) AMD Radeon HD 6800 Series
Processor: AMD Phenom(tm) II X6 1090T Processor (3.21 GHz)
Ram: 8,00 GB
Motherboard: Crosshair IV Formula

What exactly do you mean by lag?
What resolution?
Do you have MSIAF installed? Enable gpu usage, fps, in OSD
Have you tried to use single card (with disabled crossfire)? If gameplay will be smoother even with lower fps (compare with CF fps) you have a microstutter then.

Also you should verify how much both cards (or single) loaded, if it's jumps from 70(or lower) to 99 try to maximize graphics (or add 2x/4x AA), it may help to load your cards to constant 99% usage. With 99% usage I have a lot better and smooth gameplay

Lag is just like frame drops. I'm using resolution 5292 x 1050.
What is MSIAF? Where can I find it?

MSI Afterburner, program which you should have always installed from now.
http://event.msi.com/vga/afterburner/download.htm , enable GPU usage monitoring for both cards in OSD and follow my previous reply to see what causing framedrops while gaming.

I would suggest, depending on the settings that you're using, that it's a combination of running out of VRAM (those 6800's only have 1GB of VRAM IIRC) and lack of raw power for pushing a resolution that high. EyeFinity/Surround resolutions eat graphics cards for breakfast; you need to find the sweet spot for settings in each game - particularly if you're running face-first into a VRAM limitation.
