ASUS has an upcoming A8N32-SLI Premium board that has two PCI-E x16 slots running at full x16 bandwidth each. This is made possible by pairing up two nForce4 chipsets; CK8-04 and C51D together to offer up to 40 PCI Express lanes where 32 PCI Express lanes are allocated to the two PCI-E x16 graphics slots, 2 to network and RAID controllers and the remaining 4 to the PCI-E x4 slot.
