hi, I am newbie. I've been having an powercollor HD 6950 2Gb. in asus F1A75 mobo with 3870k proci. and buy the new one Powercollor HD 6950 2Gb and crossfire it. I've reinstalled the drivers and update to the latest version. but when playing games (MW3/hitman) that I see getting fps average between 34, if using single card i got 55 average fps.
*my 1st PCI-E running x16, and 2nd slot is running x4.
*there is Bottlenec issues, maybe?
any one can help me (sorry for my bad english)

Maybe you are seeing Microstuttering. I did when I ran 3850s, 3870x2, 5830s and 9800GX2. Not until I went with 600 series gpus did that go away for me. Some people are more sensitive to it then others though. OC'ing the cpu opens up bandwidth for the gpus. Its like a pipe, the more you stuff in, the slower it goes. Bigger pipe, more you can stuff it.

I also had to assume so, but why in the box says the mobo can support crossfire if there will be problems concerned with 4x slot.. tks for respond

i was post this thread in another forum, and they are told me too. it was microstuttering..
so if i upgrade my mobo and cpu to higher spec. still i see microstuttering on my dual GPUs? consider i.e i got i7 4770 + MSI Z87-G45 Gaming mobo
