My early take on it (just finalizing my OS installations now)... good Quad overclocker with tons of BIOS options, good upgrade path with Penryn mated to DDR2, good for Crossfire with 2x16 PCIe2.0 slots, problem with Vista 64 if you install EPU drivers & AI Suite from MoBo disk (go directly to ASUS download site for current EPU drivers & AI Suite), shortage of PCI slots if you go with two double slot video cards, decent "on board" audio card, no eSATA. BIOS revisions coming out frequently, somebody at ASUS likes to tweak this board.
