Hello,
I bought Battlefield 3 some days ago. After I'm getting into a game (No matter how many players it has) its stuttering every 2-3 seconds. I tried all various Graphics Settings and VSync but none helped.
My Specs:
AMD Phenom II X4 955 oced @ 3.4 Ghz
Gigabyte HD 7950 Windforce 3x
8 GB RAM
2 TB HDD + 128 GB SSD
530W Power Supply BeQuiet 80+
Cooler Master HAF 912 Plus Case
What I tried already and didn't work:
Vsync on/off
Changing Graphics Settings
Disabling Cool n Quiet and C1e Support in BIOS
Reinstalling Drivers

if you cpu is not oc'ed, oc it to ay least 4GHz. BF3 MP will bottleneck the 7950 but SP and Coop will be fine at 4GHz,

a stock or low oc deneb will not feed the 7950 enough. not sure what mobo you have but here is guide . . .

get that 4. maybe a cololer master 212 with 2 fans will help cool it. the 912 is airy, so just need some tweaking.

edit: btw, i had a windforce (rev1) with no boost. if you have the new one (rev2) and has a boost - try disabling the boost. not sure how but try moving the switch on top of the card to switch 1 or 2. turn off your rig first.

i love my 912. move the switch to other direction and see if it is the boost that's causing it.

the one on the top of the card near the bracket (front). it is very tiny. turn off pc and switch.
