Nforce 650i is not something brand new and we mentioned this Nvidian chipset here. EVGA was the first to announce the real board based on it.
It is based on Nvidia reference design and cooled passively, southbridge is not cooled at all but has holes and place for a fan. You should get one only if you decide to overclock the board.
The chipset supports Intel LGA775 800/1066 and upcoming 1333FSB Conroe processors, up to 8GB of dual-channel DDR2-800, four SATA connectors, Gigabit Ethernet with FirstPacket technology and High definition audio. The board has PCI-Express x16 slot, two PCI-Express x1, and three PCI slots.
Price of the EVGA Nforce 650i Ultra goes a little over the estimated $99 price as EVGA's MSRP is $129.99 USD, but EVGA way always walking on the expensive side, so this one shouldn't be any different. Actually there are two versions of the board and the only difference is that the second one has 4 USB ports while the first one has 8.
