Whats your CPU running at durring this? MP is much MUCH more demanding of CPU.

Pretty sure the cpu isnt the problem. When i first installed the card I was running the cpu at 3.6ghz. Now I've bumped it up to 4.6ghz and im still getting the same gpu usage % (about 40). Don't think bf3 could bottleneck a i5 2500k at 4.6

What resolution are you playing at? And in some cases, an overclocked 2500k can actually bottleneck in BF3. The game is best with 6+ threads.

What are you smoking, my 2500k easily out performed my amd 6 core in bf3.

yea I dont think an amd 6+ has anything on a 2500k @4.6 in regards to gaming performance.

No game uses more than 4 cores. End of. Not a cpu problem, has to be a driver problem or faulty card. I would just reiterrate what someone else said, search and keep changing drivers until you find one that works, and just stick to that.

i would just reinstall Windows 7, if that doesnt fix whatever issues then just sell the 4870x2's. There is no way there is a bottleneck with the 2500k.

Sometime you just need to reinstall Windows 7, especially for ATI Drivers when you start a new CFX config, I had to do it before myself and the problem was fixed.
