Core™ i3-3220 Processor Bundle w/ Asus P8B75-M/CSM Motherboard + Gigabyte HD 7850

The fps of Crossfire na is only 130-140, its low.. why?

The driver of video card is up to date.

More about : hd7850 low fps

You have a relatively high end card but you have a relatively low end CPU to go with it. That may not be your only problem, but it is probably one of the larger ones holding your video card back.

We need more information. Resolution? Game? So you have two 7850?

It definitely shouldn't bottleneck, unless you're playing on low settings or an old game. i5-2500k would bottleneck HD 3000 on CS 1.6 for example.

yeah, I realize that. But is there any method to boost fps without large cost? like change another motherboard or cpu?

I don't agree with cl-scott. i3 will not bottleneck HD 7850.

this is a bit old game, I was using my friend's pc with i7 and another motherboard, and 7850, the fps is pretty good with stable 210+

Well, of course the i7 will get better performance. But how is 130-140 fps low? No monitor can display that many frames per second anyway.

When I was using 9400 gt + E7440, the fps was 120-130.

What's your CPU usage like? What about performance in other games?

Could be CPU-heavy and that's just what you get. Like Sunius said, it really isn't an issue since it's well above the monitor's refresh rate. If worried that it's not behaving as it should, check Tom's benches for a GPU-heavy game and compare with your friend's i7 system.

I didnt try it out in other games, the usage is about 30%

nah, I did closed everthing before I played this game, and I made the peformance max in video card setting.

I heard some game with fps around 0-30, but this game is always around 0-250

Sounds like this game or your system is CPU limited...

Seeing as you are getting the same FPS going from a weaker GPU and a stronger CPU (Xeon E7440 2.4GHz quad core server processor) to a better GPU and a weaker CPU (i3-3220 3.3GHz dual core processor).

Here, found this:

http://www.tomshardware.com/charts/cpu-charts-2012/comp...[5772]=on&prod[5775]=on

Note that there is a 20fps difference between an i5 750s 2.4GHz (4 core) system and i3 530 3GHz (2 core/4 thread).

i5 @ 102fps
i3 @ 82fps

And this i3 has hyper threading and your doesn't. So yup, CPU limited.

Definitely NOT CPU limited. The CPU usage would be higher: 30% is not even fully 1 core loaded.

@OP: And what is GPU usage like?
