Asus is getting ready to announce yet another Nvidia-based AMD motherboard, although this one comes with a slight twist, it has a PCI-X slot. PCI-X is generally found in servers and workstations, and as such the name for this upcoming motherboard is the M3N-WS, WS standing for workstation. We're not quite sure if this board will use the 780a or 750a chipset, as it's hard to tell just by looking at a picture, but either which way, this board features an N200 chip. The rest of the slots consists of a x16 PCIe, two x1 PCIe and two PCI slots.
