Verdict

The Gigabyte G1.Assassin 2 is an E-ATX gaming motherboard built on the Intel X79 Express chipset and LGA 2011 socket, specifically designed for high-end Sandy Bridge-E processors like the Core i7-3960X. Key technical characteristics include a 4-channel memory architecture supporting up to 32GB of DDR3 (up to 2133MHz), three PCI Express 3.0 x16 slots for 3-way SLI or CrossFireX, and 8-phase digital power control for the CPU and memory. Its main pros are the integration of premium dedicated hardware, such as the Creative Soundblaster 20K2 audio processor with Nichicon MUSE capacitors and the Bigfoot Networks Killer E2100 LAN with its own NPU and memory, alongside bundled extras like a Bluetooth 4.0/Wi-Fi expansion card. On the downside, the board only offers four DIMM slots instead of the eight found on many competing X79 boards, lacks a debug LED or onboard power/reset buttons, and some users found the initial 3D BIOS interface and bundled software utilities to be clunky.
