the point I think he was trying to make is that most "stock" clock ones should be able to OC as easily as the factory ones (assuming one does it right, testing & cooling, etc), yeah sure the factory ones have slightly better coolers sometimes, tested & a warranty to boot, at those clock speeds, but thats about all there is between them.
in any case, as far as this thread is concerned, has nothing to do with comparing stock vs factory OC'd models, as I pointed out in the previous post, the Alpha Dog model linked to isn't Factory OC'd, just stock clocked with the Alpha Dog moniker slapped on it.
