"Asus saw the need for an enthusiast-class motherboard based on the P35 chipset, but with a more flexible PCI Express configuration. And leveraging what they undoubtedly learned from designing the PW564-WS , engineered the Blitz Extreme and Blitz Formula motherboards, complete with a PCI Express switch that allowed them to connect the P35 Northbridge's PCI Express lanes to not one, but a pair of PEG slots. Asus didn't stop there, however, and also outfitted the Blitz boards with a hybrid air / liquid cooling apparatus and a number of other features that are sure to please."
