Great prices. Newegg is terrific, but it does not say on the page what the guarantee on these processors is, but even a 15 day warranty would be a help. Ususally if it is dead, Newegg will say that on the page. These are probably customer returns. I did buy a refurb mother board from them and it arrived DOA, they replaced quickly at no charge with a Hot swap. Let me know if you find out more info on the return policy on these.
