Both CPUs are guaranteed not DOA (buyer pays return shipping if there's a problem, will refund BTC upon receiving), shipping is free in the lower 48 states (contact me for shipping costs to other locations). I've been buying and selling on eBay for over 12 years; if you'd like to see my seller feedback, let me know.

Prices may change to reflect currrent market value, but they are also OBO. Post here if interested (or private message me on the forum for payment address/your shipping address), I will post pics if need be.
If this goes well, I have some other hardware (DX10 GPUs, DDR2 RAM) I might be willing to sell for BTC.
