Taiwan-based Micro-Star International (MSI) presented today N280GTX OC HydroGen, the company's fastest clocked, water cooled GeForce 280 GTX card. The card is said to run the world's highest core clock settings at 700MHz, a boost of 17% over the default 280 GTX core speed. That's achieved by the full cover water block of course. Its micro-channel design allows for that speed to be achieved, while maintaining working temps of under 40'C. Another advantage of this water block is its single slot design, allowing for easier multiple video card installation. No price tag or retail availability were announced by the time of this post.
