PCIe slots in 5860
We are considering getting a new 5860 workstation. We need to install two PCI cards (PCI x4 and x8). The x8 card is a bit larger in overall size, so I am concerned whether some slots may not fit in. The 5860 has five PCI slots with 2 x16 and 3 x8. Based on the image of the motherboard, I am sure that this is how slots look like:
slot 1: x16
slot 2: x8
slot 3: x8
slot 4: x16
slot 5: x8
One of the x8 is described as x4 electrical. Does anybody share information on which slot is x4 electrical?

It's SLOT 3, PCIe x8 slot wired as x4 electrically. See description for #28 of system board callouts.
