Does anyone know of any "issues" or special considerations regarding the AMD XP chips in the 1600-1900 range. I will be building some systems and plan to use whichever chip gives the most bang for the bauck at the time. Are any of them know to be "bad" .. ie unreliable, prone to overheating, etc. I imagine the speed differences are negligible, but, if any one knows differently, please comment.
