You could just as easily have solved the problem by replacing the motherboard since you went to a socket 1155 MB. Example, let's say I was seeing low FPS with my old rig which consisted of a Phenom II and 7xx series MB. I replace it with a brand spanking new i5 and new MB yet keep my old GPU. Now I have higher FPS and it would be really easy to say "well it was slow before but it's faster now so i5 is better. But is that really the whole story? Was it really the old CPU causing the low fps? Or was it the old MB's reduced PCIE bandwidth compared to the new board? First you have to look at the system as a whole and then determine what exactly is happening while you're seeing a dedgradation in performance.

Dang dude. You are absolutely correct! I mean that makes so much sense... If it was actually what happend in my case...
Too bad that wasn't the problem... the problem was that an amd cpu can't keep up with dual cards. Don't let ur amd fanboyism get to ur head. That's good to have pride in what u like. More power to u. My mobo fed x 16 2.0 bandwidth to each card... I'm not jumping the gun I'm explaining my situation. If my cpu usage was at 100 percent pretty much and my gpus were no where near that there's obviously a bottleneck. I don't get the laughing at the ivy bridge cpu.... An amd cpu will cry and blow up if it gets anywhere near that.
What's really funny is that my i5 was feeding my 6850s x 8 2.0 to each card and my thuban gave them the full bandwidth at x16 2.0. The I5 gave more performance and fps with half the bandwidth :/
I hope u enjoy ur new machine op please post back in this thread and let us know what ur stock cpu usage is on bf3 and how it handles the 670. I can't wait to find out about the no bottleneck ^^.

so then I must be sore Lollllll. My old mb was an asus 790fx deluxe m4a79t. My ram was my signature ram. My overclocks passed over 12 hours prime blend with 90 percent RAM usage. I've used multiple drivers and caps for crossfire. I used 2 different bridges. I did fresh install of Windows. In games like league and hon everything was fine because they weren't cpu heavy. All voltages were accurate to the manufactures specs. I used msi after burner to stress my cards and there were no bsods, artifacts, or freezes.
You can lead a horse to water.....
but it's his money to spend. At least he'll solve his MB problem
