from completed build tggrng123

The performance out of the box is great! I've not had quicker rendering times than when I've got this CPU. With audio production, even the most CPU taxing VSTs hardly load it! I am disappointed, however, as I wasn't able to overclock at all with the one I received.

Super fast yet efficient processor, I'm glad I choose this over the AMD FX Series.

Very fast, runs a little hotter than my 4690K did though.

Definitely, I wanted an i7 for the workload but x99 platform, 6 to 8 core intel cpus are way out of budget.

from completed build First Gaming Build - $1700

What can you say? 8 threads at the ready. Fast and reliable.

from completed build Mighty Midget

First time in since the slot style cpu I have used INTEL, I always like overkill :P 4.4ghz no issues and its undervolted my my motherboard and stable

very hot cpu but fast for gaming

from completed build RedRanger - First Gaming PC

CPU has worked flawlessly since the first start automatically turbo boosting itself to 4.4ghz.

from completed build The Black Ghost

What a beast. Crushes everything I've thrown at it thus far with room to spare. Highly recommend for anyone who can afford it, you will notice the difference.

See the Benchmark in the description of my build. Great power, great value, no OCing required.
