There are quite a few threads on crossfire on the 1st page now with loads of info. Have a read and come back with any additional questions.

I can tell you off the bat the you don't need CCC for crossfire to work as I found out today. Just installed my x2 6870's with the display driver only and both cards are working fine, temps are amazing too.

Getting the PC to pick up both cards i have found can be bizarre, it for me either didnt detect card 2 or fired them both up full fan speed and didnt detect any of them. Best advice is get it working with 1 first with a few reboots then add the other one but dont put the strip on, reboot again and this time add the xfire bridge.

You sure CF is enabled though? The only way to tick that box is VIA CCC unless it defaults to on without it?

You can check by running MSI Kombustor and check temps of both cards.

ive alrady read the info that is on the first page, but most people dont have the system that I have and 4 monitors so, my question is IS crossfire going to be a step up and imprive performance, or should I keep the graphics cards indenpendent of eachother.

In terms of setup, both cards are up and running with all 4 monitors fine, that was easy as the AI on my system sorted that out for me and then I just calibrated the position of the monitors....

Default to XFire. Both cards running under full load on WoW and CoD4, i'm guessing it'll work with every game too. Just installed the display driver and that's it, working fine out of the box.

Problem with that though is what if you want to disable it? Not all games run better in CF mode. Some actually run worse, like WoW unless later drivers sorted that out? But still you'd want the ability to disable
