I read it as PCI-e slot #1 X16 when used alone, X8 when slot #2 is also used. Now PCI-e slot #2 is x8 when used as well as PCI-e slot #1 but what I don’t know is if slot #2 is x16 when used alone.

The whole point of this PCI-e test was to find out if maybe slot #2 was maxed @x8 and if so the when in crossfire with both slots running @x8 if this could be the cause for the low 3d06 score?.
Now that's what I'm talking about.

Sure looks like slot 2 is hard wired X8 and that it doesn't matter one bit even when the CPU is OC'd. Now go do the same thing with the Heaven benchmark using DX 10 setting....
