Jetway has very quietly released what to our knowledge is the first AMD RX780 based motherboard. The RX780 is a low cost chipset from AMD with support for the AM2+ socket. The board in question, the A780G, features a single x16 PCI Express slot, a single x1 PCI Express slot and four PCI slots. The RX780 is paired up with the SB600, as the SB700 won't be ready for a couple of months or so.
The general layout is a bit Spartan, with four memory slots with support for DDR2 800, four SATA ports, a single IDE and a floppy connector. The board lacks legacy ports apart from a pair of PS/2 ports, although there seems to be headers for at least a parallel port and most likely a serial port on the board. It appears to have four rear USB 2.0 ports and it's got Gigabit Ethernet connecter via PCI Express. It's also got 7.1-channel sound, but it seems to lack S/PDIF connectivity.
It's quite odd to see a board with four PCI slots in this day in age, but it might be a good option for those with a fair few older cards such as TV-tuners, sound cards, video capture hardware etc. Jetway is apparently offering some overclocking features for the A780G. We have no idea how much this board will cost or when you'll be able to buy one, but you can have a look at the full specifications here
