Upgrade advice (find the bottleneck)

[teddypwnage]

Hi all, I am looking for my next piece of hardware to upgrade for my GAMING DESKTOP. budget $100-$300 (there isnt too many reasonable hardware components out of this range). but im basically looking for the bottleneck (I'm guessing processor or MoBo)

Rig:
1000W cooler master power supply
Nvidia 790i Tri Sli mother board,
EVGA 460gtx (just bought - woot!)
Intel Core Duo CPU E8400 @3GHz (both of em)
4GB of DDR3 (i believe GSkill 1333)

I just bought BF3 and the processor hits 95-100% constantly (not good?), memory also hits about 75%, but thats not too bad..., but perhaps the mo-bo is really the bottle neck. also, if its possible to have a free solution im all ears.
SUGGESTIONS?? Thanks ahead of time.

BF3 cares little for cpu power. http://www.tomshardware.com/reviews/battlefield-3-graphics-performance,3063-13.html This is tom's review and as you can see there is almost no cpu scaling. If you want to get more out of BF3 I'd grab another gtx460 and SLI them.

From the numbers you posted it's not unreasonable to deduce that your bottleneck is the CPU. Is the game playable? If yes, I'd save up a bit more. If not, you can get an AMD X4 system for 300($? you didn't specify currency).

not really looking to increase the performance of BF3 specifically, just in general im asking all what part they would upgrade next. And also if that 95% CPU usage is a problem or not.
