yeah i downloaded it but i really dont know how to read the chart, and i herd that if you play the game under window mode crossfire doesnt work, when i put it to full screen i cant see whats going i on, i clicked on record but i cant find where it goes.. and when i played on full screen it lagged extremely badly... like it was all choppy then the game finally closed down.. my processor is a i7 920 2.67ghz liquid cooled, im getting kinda pissed off somone tell me what can i do to get better performance before i start O/C the crap out of my pc and end up frying it.

Isn't this shown somewhere in ATI's CCC control panel?
Also I would think you can run 3D benchmarking software to verify the use of Crossfire on your system...

Make sure crossfire is enabled in the CCC. If you do not do this only one core will work.

yeah its enabled, but my game is still laggy and choppy at full screen, my fps runs from 64 to 28, they suggested for me to disable crossfire and u use one gpu, when i did that the game and comy computer crashed down.... my screen would turn black in the first couple of seconds and i would have to manually turn of my pc...

It's possible that the game simply isn't compatible with Crossfire mode. Did you try other games?

no i tried it with 1 graphic card, it didn't give me that problem when i had it on crossfire, only when i used with 1 gpu, this other guy told me he had the same problem with the 5970, and yes i played other game, battlefield 3 is the first game that giving me problem

Well, you should understand that the Battlefield 3 Beta is... Beta. So there will be issues in the game that you should be reporting to EA, such as graphic issues. Mind you, I am in beta and had it crash out, but it also insisted that I be on beta drivers as well, not the current stable release drivers for my nVidia card.
