What resolution are you playing in?
Battlefield may not run great on ultra settings with a 660 regardless of SLI.
Try turning down the settings and see what happens.

Thanks

Load should be much more than 50%. You don't have vsync on do you? What drivers do you have?

Your cpu can't keep up.

You need to overclock it, and even then you will never get the full usage out of both 660's.

You need an i5 to properly use 2 powerful gpu's like that.

I agree, your CPU is holding you back, you need to get a CPU cooler (best one for the price would be a hyper 212 evo ~$30) and overclock your cpu to 4.2GHz+ , or buy a new CPU+Motherboard (i5 would be best), or live with what you have.

How would my old radeon 7850 2g oc card do just fine but the nvidia cards won't get those frames

In bf3 they are similar in performance yes with SINGLE GPU's.


With multi GPU's the overhead kills the amd processors, they cannot feed both cards information fast enough.

So if i update to the FX8350 i should not have these bottleneck probelms?

The 8350 is basically only around 10% better than the 8150 in bf3 at equal clocks.
