Introduction, Features and Specifications

Intel’s G33 chipset is a great option for users either looking for a low total system cost or maybe the beginnings of an HTPC or SFF system. Come in and read how the Gigabyte GA-G33M-S2H board could work for you.

For as long as I can remember, multimedia and gaming enthusiasts have had to endure using mediocre micro ATX motherboards for their HTPCs and LAN rigs. Motherboard manufacturers were forcing consumers to choose between using larger ATX motherboards with loads of features or micro ATX boards with the bare minimum to run their applications, programs, and games. This wasn’t entirely the fault of motherboard manufacturers, but they do take some of the blame for what features they choose to incorporate into their boards.

In May, Intel released the G33 Express chipset that supports the latest multi-core processors up to 1333MHz FSB and the upcoming 45nm platform. This chipset was also developed to support the latest high-definition video capabilities as well as support HD DVD and Blu-ray technologies. Gigabyte has taken full advantage of this chipset’s performance capabilities with the GA-G33M-S2H. This mini mobo packs a large punch and features a host of other features that should excite both multimedia users and gamers alike.
