As reported last month, Gigabyte has been working on a premium motherboard brand targeted at high-end gaming PCs, rivaling the Republic of Gamers (ROG) series from ASUS and Big Bang/XPower from MSI. One of the first products in this lineup is called "G1-Killer", and as it turns out is a socket LGA1366 motherboard based on the Intel X58 chipset. Gigabyte continues to tease us with new "cutout" pictures of the upcoming product. The latest poster shows a portion of the motherboard revealing the heatsink over the southbridge area, which is shaped like a 5.56 magazine, with even a round sticking out. One can also faintly see the six memory slots, four PCI-Express x16 slots, eight SATA ports (probably six 3 Gb/s and two 6 Gb/s). Said to be unveiled at CES 2011, the G1-Killer range is expected to start at US $299.
