TPU found some photos of the upcoming M4A89GTD Pro USB3, this motherboard is expected to be shipped ahead of the launch of AMD's six-core Phenom II X6 processors.
The M4A89GTD Pro / USB3 is a socket AM3 motherboard with a 10-phase CPU VRM supporting future AMD CPUs with 140W TDP, 2-phase memory VRM powering the four DDR3 DIMM slots, AMD 890GX chipset with faster DirectX 10.1 compliant graphics, and AMD SB800 southbridge. The SB800 provides six SATA 6 Gb/s ports, while an additional JMicron-made controller gives out the IDE connector (and possibly the lone eSATA port). Expansion slots include two PCI-E 2.0 x16 slots (x8/x8 when both are populated), two PCI, and one each of PCI-E x1 and PCI-E x4. Connectivity includes 8+2 channel HD audio with optical SPDIF output, gigabit Ethernet, USB 3.0 ports (on the USB3 variant), FireWire, and display connectivity including DVI, D-Sub, and HDMI.
