Well it looks like AMD has taken their Fx series to another high without increasing the core voltage. now running at 2.4 ghz. this is one mean chip but you can read more herehttp://www.legitreviews.com/reviews/fx53 turns out this chip can run at 2.6 with little problem. I think it time for Apple to at least start putting those older G5s in every product and release those 90nm G5s in powermacs. If not it will be the G4 game allover again. By the way this is a 64 bit CPU from AMD.
