In the first of a three part Asus X79 Motherboard series, we introduce to our readers the flagship ASUS Republic of Gamers Rampage IV Extreme. Built and tuned by a world-class team of perfectionist engineers and megahertz thirsty overclockers from the ROG team, this new Rampage could turn out to be one of the all-time greats in the history of enthusiast tech.
