With a Quad core yes, our board tops out at 485, on high FSB capable dual core CPU's going over 480 is quite easy (for benching not Prime). Trouble is not many people run dual core CPU's on these boards (there are some but Quads are the money shot). As said in the AT article, the board suffers due to a lack of GTL tuning adjustment for Quad cores, with longer Prime runs giving up the ghost circa 460FSB.
