The GA-m750SLI-DS4 is a high performance model and step-up from nVidia's original nForce 750a SLI Chipset. It features AM2+ platform support, HyperTransport 3.0 technology, and an integrated DDR2 1066 memory controller. Part of the Gigabyte Ultra Durable 2 series, the GA-m750SLI-DS4 is built on an AMD64 framework and includes several upgrades including higher data bandwidth, superior processing speed, and Hot Plug support which permits users to plug and unplug hard drives without powering down their computer. This motherboard also incorporates optimized power savings, extra cooling, increased durability, and 128-bit Floating Point units. Furthermore, critics cite its PCI Express 2.0 and dual x8 connectivity as outstanding for top-notch game-playing performance.
