A little earlier, we were treated to pictures and details of the Gigabyte G1.Sniper 3
motherboard based on Intel Z77 chipset, supporting LGA1155 "Ivy Bridge" and "Sandy Bridge" processors. Presenting, Gigabyte's first G1.Killer series motherboard in the micro-ATX form-factor, the G1.Sniper M3. This new board is based on the same Z77 chipset, and is backed by a fairly exhaustive feature-set that makes it a formidable high-end micro-ATX gaming desktop choice (good for LAN party rigs). The LGA1155 socket is powered by a 9-phase VRM, which draws power from a 4-pin ATX connector (instead of 8-pin EPS). The socket is wired to four DDR3 DIMM slots, supporting dual-channel memory.
Out of the four expansion slots this form-factor permits, three slots on this board are physical PCI-Express x16. The topmost one is PCI-Express 3.0 x16 (x16/x8), the bottom-most one is electrical PCI-Express 3.0 x8. These two slots are wired to the CPU. The x16 slot in the middle of the two is electrical PCI-Express 2.0 x4, wired to the Z77 PCH. Then there's a PCI-Express 2.0 x1, also wired to the PCH. SATA connectivity doesn't rely on any third-party controllers, internally there are two SATA 6 Gb/s ports, three SATA 3 Gb/s, the fourth 3 Gb/s port is wired out as eSATA, on the rear panel.
Further, the board doesn't rely on third-party USB 3.0 controllers. There are just four USB 3.0 ports, two on the rear-panel, two via front-panel header, all four wired to the PCH. Like the G1.Sniper 3, this board lacks fancy Creative or Bigfoot made connectivity. It makes use of Creative Sound Core3D audio, which is backed by amplifier circuitry that's better ground-isolated from the rest of the motherboard; and Intel 82579V gigabit Ethernet. Display connectivity includes one each of DVI, D-Sub, HDMI, and DisplayPort. A number of USB 2.0 ports top it off.Source: VR-Zone
