Hey guys, I 've had two 7770s in crossfire for a while now but I still can't solve my problem: Games have a weird lag in them making it very uncomfortable to play. Windows Aero and browsing lags too. Drivers and CAPS are at latest and I tried everything from 12.8 on. My 6670 never had a problem and if I disable crossfire and try the cards out on their own, the lag stays with both of them.

My specs:

FX8120, Sapphire PB 990FX, VTX3D X-Editon 7770, Gigabyte 7770. I'm thinking it's a faulty motherboard (the third of three woohoo!) but what do you guys think? The motherboad sucks badly, the power LED is broken and the bios is absolutely horrible, making crossfire no working when the Marvell controller is in use.

Here's a video of what I mean of the lag: https://www.youtube.com/watch?v=TFxIFYgpkZU

Have you tried a complete un-install of CCC followed by running Driver Fusion (in safe mode and w/ elevated privileges) then installing the current version release of CCC?

No but I had to wipe boot drive once so I installed the drivers completely new anyway.
