If upgrading CPU, does it have to be New or can it be used?

It can be used, I've seen i7 2600k go pretty cheap. Nobody here likes to seem to talk about the great deals you can find used though. Shouldn't have a problem when buying from a good seller.

Idk why people would spend the money on a new i3 when you can get a sandy bridge or even ivy bridge locked i5 on ebay/amazon for a tiny bit more money.
