I have an Intel i5 3570k and I always wanted a CPU that can handle 1080p 60fps VIDEO RENDERING, not gaming, and not step above 50% usage in the task manager. I am also looking for extremely fast render time. With my i5 3570k currently when I render 1080p 60fps videos it takes about 2 hours for a 30 minute video. I heard the i7 5960k can handle these 1080p 60fps video render pretty well - whatever the length of the video is, it can render in half that time. I am looking for a CPU that when rendering videos renders incredibly fast while also not reaching anywhere near 100% CPU usage. Thank you!

UPDATE: I have 8gb of RAM currently, and just bought 16gb of Corsair Vengeance RAM to install over this Christmas break so I can multitask easier (Watch videos and other resource intensive activities) while rendering videos..... I am constantly rendering videos for Youtube so a powerful CPU that can handle a lot and minimize render times would be fantastic!

Not necessarily, I was more or less asking if there is a processor that is powerful enough that it doesn't need to run at 100% to handle this quality of a video render. Maybe for 4k renders, but for 1080p 60fps I thought some processors can handle that without needing to run as fast as it can (100%). Maybe I don't understand computers enough to see that I want my processor to run as fast as it can but then without a ram upgrade I also can do much more other than let it render. What If I want to do simultaneous renders without sacrificing exorbitant amounts of time? If my processor is working as hard as possible on a single render, how can I expect it can handle two without making each render painfully slow - hours more than if I was just rendering a single video.

Also what is your opinion on the Intel i7 4790k processor? It seems like a better bang for my buck.

I am not expert but why don't you consider i7 6700K or i7-5820K rather than i7 4790k?
Is there any special reason?
You can compare it on Intel's website

for rendering etc i really wouldn't go with a 4790k, id go with the 5820k, it has more cores, threads and cache, also has more pcie lanes incase you want more gpus.

If price isn't an issue you could always hold out for Intel's Knights Landing Xeon processors scheduled to be in limited supply next year.

Knights Landing, which Intel says is its most powerful chip to date, is a 72-core processor with 8 billion transistors

I am pretty sure this would get the job done.

You're asking the wrong question. Computers are either busy or not busy. 100% or 0%. If they are not busy, it is either because they don't have work to do or because they are waiting on something - like a I/O operation or on RAM (yes, computers are so fast, they wait even on RAM).

Rendering is in many cases the most-optimized workloads that many people here will run. SO, for as long as there is work to do, the processor cores will run at 100%. Up to a point - if you run a 1024-core machine, such as a Xeon Phi, it's most likely that the processor cores will not all be utilized - then you will get sub-100% utilization. For normal 4-, 6-, 8-core machines, etc. you will always see 100% utilization during rendering - getting a more powerful machine will only show the 100% utilization for a shorter period of time.. If you are rendering and you see sub-100% utilization - or 50% as you wish, then you can know for a fact some other part of your computer is sub-optimal - maybe your hard drive is too slow, or you do not have enough RAM - something like that.

The 4790k has 4 cores and 8 threads just like i7 6700k or i7 6700 then may I know on which basis you say 4790k isn't good for rendering?

(BTW I do like 5820k but my above question is still a logical question::::::::::)

As you said
"If you are rendering and you see sub-100% utilization - or 50% as you wish, then you can know for a fact some other part of your computer is sub-optimal - maybe your hard drive is too slow, or you do not have enough RAM - something like that."

The other reason could be that there are more cores in CPU and only a few (lets say 3) are are being used and rest are not so in that case: the CPU load will be shown less than 100% (may be 60%) and we think that our CPU is fast enough to handle this task, @Karsten75 I think my guess is also correct, isn't?
