Trying for the last hour to get some info on lane speed of the 2nd PCIe x16 slot and can't find it anywhere. DOes the 2nd Slot run at least at x8 if you are running a crossfire or Sli set up ?
 
thanks for the quick answer. I haven't actually got it yet, but this was a deciding factor as my next upgrade is GFX and I was going to run a pair of 6950's or a pair of 480's. However if the 2nd lane was only runing at x4 I would have looked at another board :)

All sandybridge boards sport a total of 16 lanes via the CPUs controller. This means that all boards run 8x and 8x unless they have an NF200 chip which this does not.

Hope this helps.

thanks that helps a lot. I guess that the difference in performance between x8 x8 and x16 x 16 is only going to be a few % and not anything too drastic ?

In the end I went for the GD65 also as it was on special :)
