The ASUS Maximus Formula Special Edition not only features the X38 chipset but packs a whole bunch of additional features that should help it stand out from competitors' X38 products.
For starters, the Maximus Formula is a water-cooled motherboard, which is no doubt an appealing feature for many many gamers and overclockers alike. It also includes the SupremeFX II soundcard which is another feature aimed at gamers, along with a software bundle of 3D FPS game S.T.A.L.K.E.R., a copy of 3DMark 06 and Kaspersky antivirus.
