Intel Core i7 6700K 4.00GHz Unlocked Processor (Open Box)

I had an Ivy i-3570k that served me well since February of '13. Had it @ a comfortable 4.2Ghz. Could I have held off 2+ years? Sure. But I thought to enhance the durability for my CPU for an additional 4-5 more years and do a complete build with the works (motherboard, RAM, PSU, SSD's). I completed the build about 3 weeks ago, and I gotta say, OCing this chip manually, I settled on a 4.5 Ghz @ a cool 1.25V with headroom given the new 1000W platinum certified PSU I have with a delicious 12V rail. I messed around and got to a "17%" overclock according to ASUS' BIOS by getting the chip up to 4.7GHZ @ 1.42V. via OCCT, but crashed about 5 minutes in. Some room for improvement, but with a premium cooler (I prefer liquid) and a top shelf thermal paste, temps are a chilly 26°C on idle, 45°C on gaming load, and 60°-65°C on stressing levels (4.5Ghz, mind you).The only con I have of this chip is that it doesn't cook me breakfast! *gigglesnort* Seriously though, if you have the means and the desire, get this CPU and you will not regret it.At the end of the day, to each their own. I upgraded to 'Skylake' out of sheer desire, not out of necessity. You WILL love this chip if you are coming off of anything older than my previous chip (Ivy) such as a Sandy, Pentium, or AMD equivalent processor. I'm delightfully satisfied with this CPU in terms of performance improvements, the hyperthreading (coming from an i5) for multiple app tasks, its overclocking potential, and its temperatures. I recommend it to you without a doubt, as long as your budget can handle the additional required hardware you may need mentioned in paragraph one.My 'Skylake' build specs and some pictures:*CPU - Intel i7-6700K (4.5 for now; not in a hurry to increase it)*CPU Cooler - Corsair H110i GTX AiO Liquid cooler (My H100i broke, I upgraded to the H110i)*Motherboard - ASUS Maximus Hero VIII*RAM - Corsair Vengeance LPX DDR4 16GB (3000 Mhz)*GPU - ASUS STRIX 980TI 6 GB (OC edition)*Chassis - Corsair 760T Graphite Series (White Edition)*Storage - SAMSUNG 850 Pro 256 GB SSD (Boot drive), SAMSUNG 850 EVO 1 TB SSD, Intel 750 Series NVME SSD 400 GB*PSU - Corsair HX1000i (80+ Platinum Certified) (A bit overkill for non-SLI, but I got a good price for it.)*Fans - Corsair AF120's (x2) and AF140's (x4), White Edition LED*OS - Windows 10 Home, 64 Bit
