For beginners, there will be nothing difficult in installing this processor.
The socket is of high quality, the processor is installed securely.

Intel Core i7-6700K Desktop Processor

It doesn't run hot even when under load and turbo boosts normally to 4.2 GHz automatically as well.
Got it at a good oc of 4.25 very fast and really good integrated graphics.
The onboard HD 530 graphics are awesome. This is a great investment and the core of a machine that will be kick-ass for years.
This is a super smart and solid option for gamers because of its high speed (4.2 turbo boosted) and unlocked allows you to squeeze even more free performance out of it.
Great CPU, really fast. Great socket.

What customers say about "Technical Specifications"

Intel Xeon E5-2665 CPU Processor

This processor has 8 cores and 16 threads, which is super. I recommend this.
This processor has excellent multithreading. I run all programs freely.
Thanks to Intel for a good processor. It supports virtualization and is very powerful. I am satisfied.
I would like a higher clock speed of the processor, at least up to 3.5 GHz.

Intel Core i7-6700K Desktop Processor

I7 quad core processor will be more than enough muscle for any and all modern games, and probably leave your gaming rig sitting pretty years of games considering that games are much more gpu dependent.
This is a super smart and solid option for gamers because of its high speed (4.2 turbo boosted) and unlocked allows you to squeeze even more free performance out of it
Quad cores also allow worry free gaming performance while still being able to run other programs and not take a hit in performance when your computer is under a heavy workload!
Awesome cpu, really fast and good temperatures.
Seems to run hot, even with multiple thermal paste applications.

What customers say about "Cache And Memory Specifications"

Intel Xeon E5-2665 CPU Processor

I liked the fact that the chip uses 4 channels of 1600MHz memory, it's fast.
The cache size is just huge, really great processor.
I chose this processor because I can now supply a lot of RAM.
64GB of RAM is not a problem for this CPU, it is fast.
A good processor for a server or home PC. The L3 cache size is really cool.

Intel Core i7-6700K Desktop Processor

The CPU has 8MB of smartcache that is shared amongst the cores. This is much better than normal cache, it allows a program in cache to be shared with another core, when the thread jumps to a new core, without copying the data to another location in cache.
Fast processor when powered with a good socket 1151 motherboard and enough memory.I have an ASRock Fatal1ty Z170 board and 32GB corsair DDR4 memory as well as a smile on my face
Everything is faster opening and switching programs games are amazingly faster was surprised how much better they ran maxed out with this chip. But also this makes the jump to DDR4 so memory has been tremendously improved stock memory is 2.2Ghz to 2.4Ghz.
It works fast, stays cool, and the ddr4 memory helps things stay zippy.
Would have been nice to have 12MB or more of cache, but the cost would have been significantly more. For the price, there is really no downside to this CPU.
