I3 540 bottleneck

Hi first time on the forums but here's my issue.

My specs i3 540 stock , gtx 570 twin frozr iii , 8gb ram. I'm getting about 40-70 fps on 1920x1080 and low graphics in battlefield 3 so is it my cpu? as I just got new ram today and I have low fps. My gpu runs at 48c at load in BF3 and I've run prime95 and my cpu reached 60c so over heating couldn't be a problem. Asked a few people about the cpu being the bottleneck and they said it wouldn't be the cpu?

Thanks

I disagree. The weak link in your system is the i3-540 processor. The dual core i3 CPU is only about as fast as the older Athlon II X3's.

What resolution is your monitor? BF3 is a very demanding game at higher resolutions.

My monitor is 1920x1080 , my 8gb ram seems to have helped but not constantly. Sometimes I get under 60 fps and then other games I get 90-130fps.

That would be consistant with some bottle neck presented by the dual core processor at that resolution. I would suggest a CPU upgrade to whichever quad core LGA 1156 CPU your budget allows.

I forgot to add, that the reason some games are presenting much better frame rates than others is because some games are CPU intensive and some are GPU intensive. Some, like BF3 are so demanding, it requires both a high end CPU and GPU for high frame rates along with near max settings.
