At work I'm trying to categorize a few elderly computers. Among them is a Pentium lll Xeon 1.2 GHz. I don't know the Xeon at all, is it faster/slower than Celeron at the same speed? Also I have been asked if a Pentium III 600 MHZ is as fast as a Celeron 800 MHz with equal amount of RAM. Does anyone know? Regards Vidal
