Yo guys, i just wanted to know some stuff about the 1800+ series of the athlon. Apparantly there are like 4 editions. One that has .18 micron core, one with .13 micron, and one is rev B, and one is rev A. And i heard that the rev A is bad, and the rev B is awesome. Now which one is the thoroughbred? isn't it the one with .13 and rev B? My athlon xp 1800+ is green, what does that mean then? Ok thanks. BTW, I purchased my athlon very recently, and it was boxed.
