I see several motherboards out there with 2, 3, 4, and even 5 PCI 2.0 slots on them. EG.,


but I've never even heard of crossfire or sli working with five (5) cards.

Can I just insert five cards and have the OS do the rest? Or do I need to somehow cable all the cards together (my last time with crossfire I had to connect the two cards with a special cable)?
