MSI has come up with a very interesting board mATX board for users who need a bit more punch in a small package.
The 890GXM-G65 is based on AMD's 890GX chipset and SB850 southbridge, hence it offers some quite interesting features, such as two USB 3.0 ports. It packs AMD's HD4290 graphics, the best IGP out there and it offers HDMI, DVA and VGA outs.
In addition to two USB 3.0 ports, it packs four USB 2.0 connectors on the back plate, as well as eight internal USB 2.0 ports. The only thing it apparently misses is SATA 6Gbps support, but since there are very few 6Gbps drives on he market this isn't a major shortcoming.
It's one of just a couple of mATX boards with two PCIe 2.0 x16 slots. Sounds like a very nice platform for a killer LAN party machine, provided you can find a tiny chassis that can house and cool two Radeons in Crossfire.
