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 Core i7-4790K CPU Processor

This is a very strong very fast chip. Great for gaming and multitasking.
Pretty decent on video editing because of the hyperthreading.
Very fast CPU, I haven't tried any overclocking yet.
It runs unbelievably fast and surprisingly cool using the stock air cooler.
The i7 is really fast and handles all of my games, video streaming, and video encoding without any problems.

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 Core i7-4790K CPU Processor

The 8 threads of execution, large cache, good overclocking ability. Great processor.
A real monster. Paired with an Nvidia 980 and 16GB of memory. Handles everything I throw at it.
The chip supports dual channel memory and at least up to 32GB RAM.

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.
