I had the same problem with SLI, truth is BF3 isn't as optimised as it should be. Even Nvidia said just that when people were thinking it was their drivers.

How can I check my CPU usage while in the game?

Sorry dude but there is... if you had no CPU bottleneck your GPU's would be a constant 99%

But why people with 7970 got 99% for both cards all the time? =(

In Medal of Honor: Warfighter I can get pretty much 95% use and more all the time even in multiplayer. But there are games like Borderlands 2, the usage is worse than using only one 670. I got a friend with 2x 7970 and a lot of games here that doesn't uses all the power from my GPU's he tells me he got 97~99% all the time, like BF3, Borderlands 2, etc...

That sounds like a huge CPU bottleneck there. You can download programs to check your CPU usage, but most people use the built in Windows Task Manager. I know BF3 is heavily multi-threaded, so you should see a majority of your cores/threads very highly used.. 80%+

BF3 Multiplayer is very CPU dependent.

Nope, I think your logic is not correct, because I didn't notice FPS increase from 4.0 to 4.5Ghz in games...

I think is a driver problem or something, but common, there was so many drivers released and my problem persists, I'm almost going to AMD side...

Because BF3's engine loves AMD. It's as simple as that...

How can I check if there is bottleneck or not? I mean, if my CPU is at % of use?
