informed us today that a new AMD chipset is about to emerge. The motherboard based on the new chipset is called M2A581-SGE and features the new AMD 570X northbridge with the standard southbridge SB600.
The board has Crossfire support and the document states it works with x16 and x8 PCIe slots. We are not sure if this is true or not, but we will check these claims.
Here you can see a picture of the board, it's quite basic, except that there is a Port 80 diagnostic display onboard.
