MSI has shown a board based on AMD's 790X chipset with support for Socket AM2+/AM2 Phenom, Athlon and Sempron processors. The "CF" in the model name means that it's CrossFire ready, so it includes two PCI-Express x16 slots for either single x16 or dual x8 configuration.
As mentioned, the board has four dual channel DDR2 533/667/800 slots which can support to up to 8GB of memory. MSI's K9A2 CF has single Gigabit LAN, 7.1 channel Audio, four SATAII with RAID 0/1/0+1,5 and a single IDE connector. Besides those dual PCI-Express x16 slots the board also has single PCI-E x1 and two PCI slots. It also comes with 12 USB 2.0 ports and two Firewire ports.
The Southbridge and Northbridge are passively cooled, but we would prefer a smaller Northbridge heatsink since 790X doesn't get that hot.
