my specs are very similar

4GB RAM @1333
AMD HD6850 1GB (about 10->15% faster than your 4870)
Phenom II 955BE
Corsair Force 3 120GB SSD
monitor i game on is 1680x1050
no overclocking

i run with BF3 graphics on auto - most settings say 'high' and get perfect framerates - never been able to feel it drop

my cpu sits at around 80% usage on all 4 cores.

I would guess that your CPU is the bottleneck. Try find a 4 core phenom II cheap if you can.

thats odd, i just ran through bf3 at 848x480, with my specs and i was getting as high as 45fps. did you make sure you set the gpu to performance in catalyst?

if lowering the res really did not help, then the cpu would be the culprit

Yea I have everything that I can set in the Catalyst to performance or off. And changing the res doesn't change my FPS at all. I can switch from Low -> Ultra and I only lose 10 frames.

Think of 1998 pentium iii is the world's TOP CPU
7 years later in 2005 this cpu is RUBBISH.

Now the same thing happens again.

athlon FX-62 introduced in 2005 with price of 1099usd as the world's fastest cpu
and 7 years later now 2012 it worth less than trash.

think of the ii x2 250 as about same performance of fx-62
(both athlon 2.8ghz x 2), using aiix2 250 is the same as using
once-top-now-rubbish fx62 cpu

above all my opinion IS:
ur 4870 = ur DDR3 4GB = GOOD
a ii x2 250 = fx-62 = USELESS TRASH

i recommend that u buy a i5 system asap.
