Atlon XP 1900+ question greets... i just saw over at newegg.com that they are selling two kinds of 1900+ processors. i'm not referring to thoroughbred and palomino, the difference is in the core. one is tagged as an AGOGA core and the other one is a regular 1900+. does anyone know the difference between these? does this AGOGA core have more overclocking potential or something of the sort? any clarifications are appreciated. i'm asking because the difference between these two is a full $13 and it seems a bit too much to pay for a proc that will run at the same speed.
