Battlefield 3 low FPS

hey, ive been experiencing low fps while playing BF3 and cant figure out why,

My specs:

CPU: Phenom II dual core, 3ghz.
RAM: 4gb 800mhz ddr2
OS: Win7 64 bit
Hard drive: 500gb SATA II

GPU:

Started with a Geforce 9600gt, obviously wasnt running it very well so I upgraded to a Geforce GT 440, also wasnt very good, I then upgraded to an ATI 6870 GPU and I couldnt notice much difference, even on medium I dont go above 40 fps, when my friends say they can play on Ultra with a Geforce 550 Ti?

Regards, Sam.

  1. your going to be asked to take your email down probably so i would just take it down for spam reasons.

    back to the question. you were right about the gpu being slow but now you have a cpu bottleneck. contrary to what a lot of the benchmarks show(they kinda hide the importance of the cpu) you need a quad core to get good frame rates in multiplayer.

    try overclocking your cpu and see if you fps go up.
  2. okay thanks, so luckily next month im getting an i7 quad core 2700k at 4.8hgz, and doing x-fire radeon 6870's this will be able to run on ultra right?:p

    thats quite the overclock, going to induce a lot of heat. have a heatsink in mind?
  4. Im thinking the corsair H100 water CPU cooler, the dual 120mm fans fit nicely in my case, might even edit the fans and put some nice blue LED's in myself, that should be more than enough im guessing?

    a noctua nh-d14 heatsink is just as good if not better then that cooler and you dont have to worry about the water leaking.
