Boards based on AMDs new 890GX chipset are starting to show up in final retail form on the web and ASUS has two models in its lineup readied up; the M4A89GTD Pro and M4A89GTD Pro USB3 (with the latter obviously including USB 3.0 connectivity).
In conjunction with the new 890GX chipset, these boards are of course AM3 socket based and use a 10-phase CPU VRM and 2-phase memory VRM with four DDR3 slots resident. 890GX also brings with it integrated DirectX 10.1 compliant graphics and AMD's SB800 Southbridge which gives SATA 6Gbps support (six ports). ASUS also includes a JMicron controller on the board that gives IDE support and an eSATA port on the rear I/O.
As you can see in the picture above, there are two PCI-E x16 slots (electronically running at x8/x8 mode when the two are in use together). Further to those are two legacy PCI slots and a PCIe x4 and x1 slot.
Rounding out the features list, the M4A89GTD Pro/USB3 includes 8+2 HD audio, Gigabit Ethernet and FireWire. Display connectivity includes DVI, D-Sub and HDMI.
Word has it ASUS plans to launch these two boards just before AMD kicks out its new six-core Phenom II X6 CPUs.
