Although Intel rendered its mainstream LGA1156 platform (Socket H) obsolete by launching the Sandy Bridge processors in January, LGA1366 (X58) has remained the company's flagship platform since its consumer debut in November 2008. There's no denying that the Z68 chipset has knocked some wind out of X58's sails, but the near-antiquated socket is still the only way for enthusiasts to get their hands on a six-core Core i7 processor.Not only does X58 have exclusive support for hexa-core processors, but it's better equipped to handle multi-GPU configurations. Without the aid of Nvidia's NF200 chip, Intel's new Z68 and P67 motherboards can only run two graphics cards in an x8/x8 setup. Because of those reasons, Gigabyte originally released its elite G1.Killer boards (the G1.Guerrilla, G1.Sniper and G1.Assasin) for LGA1366.
