Remember late last year, when AMD poured out the liquid nitrogen to boost its new Phenom II X4 to a ridiculous 5GHZ? The company's factory overclockers apparently had a lot of leftover LN2, so they invited a crew of others to come over and splash some around on a set of new Phenom II X4 955 Black processors. After burning through a ridiculous 80 gallons of the stuff they rolled out the even colder liquid helium, which led to a maximum benchmark of 6.89GHz -- more than twice the quad-core processor's 3.2GHz rated speed. In these tough economic times it's good to see that one company at least is still willing to take things to great excesses at the expense of Earth's natural resources.
