Thread Starter 
I AM NOT GOING TO INTEL!! NEVER! maybe in a few years, not now though


So I did a clean install of nvidia drivers, and no dice. Maybe even less usage.

WTH

CAN SOMEONE WITH THE SAME CPU AND SLI 460 PLEASE POST usage from bf3 PLEASE!?!?!

Do a recap of what you've tried, so we can clear things up:
SLI bridge on?
Do both cards get x16-bandwidth?
Overclocks?
Drivers?
Reinstallation of OS/drivers tried?
Good scaling in benchmarks?
It's not a specific game issue?
You're not using 1024MB RAM?

YES, bridge came with xfx psu, its on lol

both 16x

both cards at 675, 1800.
cpu at 3.9 nb 2.6

newest 296.10, reinstalled twice
not OS, not doing that

scaling in bench is 95% VERY GOOD

I think it's specific game, but still testing in games, skyrim testing right now, downloading crysis 1 demo.

gpu ram?

Sweclockers also tested CPU performance in Multiplayer with these results: http://www.sweclockers.com/artikel/14650-prestandaanalys-battlefield-3/5#pagehead
While the 2600k gained 58% more performance going from Ultra to Medium with a 6990, the Phenom II X4 was bottlenecking from the get-go and only gained 26% going from Ultra to Medium.
EDIT:
It seems people have difficulty believing BF3 is a CPU-hungry game in multiplayer, I'd advise those same people to go check their facts before making that statement.
EDIT2:
http://forums.guru3d.com/showpost.php?p=4141466&postcount=14
Another example of how hungry BF3 is for CPU-performance.

As someone who use's a 955be and a 460 SLI I can tell you you dont have a leg to stand on saying that the 955/965 cannot handle it period. Get yer facts straight.

Also, BF3 will scale up with hardware....

Skyrim fps went up, bot not enough as it should with sli 460.

I guess I can confirm the cpu is holding back. BUT STILL some others with 965 and 460, say it doesn't.

The problem is that I've got first hand experience going from a 955 to a 2500K.

I had a slight bottleneck with one 470 overclocked to 800MHz core. The usage would often slump into the 60's(%).
Went to a 2500K and even at 3.3GHz, my usage never came down from 99%.

Went SLI and the ratio is very much GPU 1.1:0.9 CPU at 4.3GHz, usage rarely ever slumps past 90% - if that were the 955, I'd be into the 50's. Granted my 955 was only clocked to 3.7, even quick death runs (C2) at 3.9 only removed the bottleneck by about 8%.

Arni90 is also correct about MP being 100% more CPU intensive. SP only uses two threads/cores FSR while MP will use 4 but you'l never see 100% CPU utilization.

Went SLI and the ratio is very much GPU 1.1:0.9 CPU at 4.3GHz, usage rarely ever slumps past 90% - if that were the 955, I'd be into the 50's. Granted my 955 was only clocked to 3.7, even quick death runs (C2) at 3.9 only removed the bottleneck by about 8%.
Arni90 is also correct about MP being 100% more CPU intensive. SP only uses two threads/cores FSR while MP will use 4 but you'l never see 100% CPU utilization.

I never said he was not correct about how CPU intensive the game is.Look at my back up and sig rig. I too have a 2500k, 955be and 460 SLI. I don't have any of the problems you guys are talking about on my back up rig:( PEBKAC?
