upgrading from Celeron to Core 2 processor

I haven't Googled the article you are talking about, but just out of curiosity does the article mention anything about heat comparison and life span?

ZiPPy

No not really because it is for over all comparison of performance when bogged down with windows and browsers stuff like that. When bogged down with desktop work the AMD won hands down.

But I would assume that as far as heat comparisson that they are about the same.

i would also quickly like to say that if the heat the processor generates concerns you, go for the 65nm models as opposed to the 90nm standards. The smaller cores perform equally well and generate less heat, they are the newer of the 2 technologies.
