crossfire in a x4 PCIE slot? - Page 3

HardOCP did a test of this, and the difference is next to nothing:

16x 8x crossfire
4x 4x crossfire

It might not be the case with the newest gen. cards, but if he is rocking 6850s, it's really nothing to be worried about.

HardOCP's testing forced both cards to the same bus speeds, but if you are rocking 16x/4x and have no issues then I'm in no position to dispute those results. Good Luck OP.

Your talking about micro stutter right? Isn't that pretty much a non-issue when you are getting FPS over 60? And if I wanted to eliminate it couldn't I set my x16 slot to run as a x4?

Sorta. It would still feel choppy if your frame rate is alternating from 90 to 70 fps every microsecond. If your FPS is always over 60fps and you use Vsync or one of those similar framerate limiting options then wouldnt be an issue. Or you could always force 4x/4x.
