Refurbbed CPU's just means they took what they had as returns and are selling them. They were returned for various reasons, and the ones that work they can just resell. I'm sure the returns are for reasons like, uhh it doesn't fit my intel motherboard, what can I do? Uhh, it wont fit my socket 7 mobo what can I do? Uhh, you mean I need a 300watt power supply for that? I can't get the heatsink on, it's too hard. What, prices dropped on AMD and I can get this $5 cheaper from another internet store? Ok I'll spend $7 and return it to newegg. Reasons like that. Most refurbed stuff sold anywhere is stuff that was returned for various reasons, and normally have minor blemishes.
