4770K vs 4930K $2300 Build: Which would you choose?

[Specops125]

So one of these builds is my rig that I built about a month ago. Another one of them is what I would likely go with if, knowing as much as I do now, I built it today. I'm curious as to what people think about each one, both for various types of tasks now and with the idea that the system will be kept (and potentially upgraded) over 6+ years. I link which one is my system at the bottom of this post.

And my build is...

 

[Outlander_04]

The 4770k build

the processor will not be the limiting factor in high resolution gaming

Yeah, I'm wondering if starting 4 years out from now, say in 2018, whether the extra cores would be making a difference then.

For gaming, an i5 will do the job, but for future proofing, an i7 would be nice; However, you only need to worry about 6-cores or more if you're doing some heavy video editing and animation. For gaming, you don't nearly need that much power
