For example, when I upgraded from my 2500k setup to a 3930k setup even at a LOWER clockspeed, my framerates in BF3 literally doubled, but that was because I was running a multi-GPU setup (3 7970s).
Either way, your CPU DOES matter in BF3.
This + 1000000000000
My current CPU cannot handle my 5830s in a BF3 multiplayer game. My minimums were horrible (sub 30). At this point in time I am running only one 5830 and although my frames are lower my minimum frame rates are much better ( above 30 ).
The reason is that with two cards my cpu was pinged at 100% all the time in any BF3 map with 24 or more players. Now with one card, my CPU stays right around 84% to 87% in 64 player demanding maps. Oh and my GPUs would only go up to 87% usage in the best case scenario (24 man maps). My setting are on "High" since I am limited by vram with my 5830s.
So yes your CPU matters in multiplayer BF3. And it is critical with 2 or more cards.
A high clocked (3.5 or more) quad core, 8gb of ram, and 2gb(ultra requires it) modern gpu will run BF3 64 man multiplayer on ultra settings over 30 FPS minimum
This is from my own experience. Basically the better your CPU the better your MINIMUM frames will be. If I paired a gtx 680 with my current CPU it will get lower minimum frames than if I pair it with my new i7 3820.
Does this mean I won't be able to play BF3 with my current CPU? No of course not. Will my experience improve with a better CPU? Yes of course it will.
Oh and I know it is the CPU and not drivers or anything else because in single player my GPUs would be pegged at 99% the entire time and my CPU usage was minimal compared to multiplayer.
