Hi,
I got an i7 4770K, 3.5GHZ, 8MB Cache LGA 1150 that I'm not using anymore. It got that Turbo Boost feature of Intel that automatically overclocks it to 3.9GHZ.
It is sold out on Newegg (

http://www.amazon.com/Intel-i7-4770K-Quad-Core-Processor-BX80646I74770K/dp/B00CO8TBQ0 Linked example costs $400 but the prize range is "7 new from $498.71" to "6 used from $346.50".
I'll sell mine for 1,2BTC/$275, where the buyer pays for shipment of your choosing. Remember that the shipping becomes much higher with the fan. It ships from Europe/EU.
If there is interest in this, I'll take pics of the CPU with fan and box with my nick and current date, along with a close up showing the inscription on the chip.
Thanks.
