Hardware Secrets takes a look on a new high-end socket 775 motherboard from EVGA, based on the new nForce 780i chipset, featuring three PCI Express x16 slots supporting 3-way SLI and other high-end features. A quote from the article:

As its name implies, EVGA nForce 780i SLI motherboard is based on the latest high-end chipset from nVidia for the Intel platform. What is new on nForce 780i is its support for the new 3-way SLI mode, which allows three GeForce 8800 GTX's or three GeForce 8800 Ultras to be connected together. Two of its three PCI Express x16 slots are PCI Express 2.0 and this motherboard has also two Firewire ports, optical SPDIF output and more. Even though this motherboard is being marketed by EVGA it is in fact manufactured by nVidia ("Designed by nVidia" program which was introduced with nForce 680i chipset), so this board is identical to the nForce 780i motherboard from XFX. Other motherboard manufacturers like ASUS, MSI, Gigabyte and ECS haven't released nForce 780i products yet, so we can't comment if they are going to just resell this motherboard manufactured by nVidia or if they will design their own products.
