Should I return the 4790k for a 6700k?

I keep reading about how the 6700k is the newest thing and how it either does the same or a little to a lot better in benchmarks, but I'm not really sure if it's worth it to return my 4790k. Here's the situation I'm in:

• I already bought the 4790k. I haven't built my computer yet.
• I plan to game, and do video editing (I'm a beginner at video editing)
• I'm planning to overclock my 4790k to 4.7-4.8 GHz
• I have a Wi-Fi card, and a 380X. In the future I may buy a USB 3.1 add on card with 2 ports
• I got the 4790k for 300 dollars, and the 6700k is currently on sale for 390 dollars
• I will NOT be using the CPU's built-in graphics
• I already bought my motherboard and RAM, but this doesn't really matter since I'd just return them with the 4790k and it'd only cost me 10 more dollars at most
• Finally, I plan to continue using this computer for a few years into the future, 3 at least, 5 at most.

So with all this said, I don't know if I should return my 4790k for the newer 6700k and get the extra IPC and smaller transistor size, while having room for an upgrade to 64 GB of RAM, or if I should just stick with the 4790k.

EDIT: 5820k is off my list, the 2011-v3 motherboards are pricey, pricey, PRICEY

Personally I don't think it would be worth the hassle of returning everything. In terms of 1151 being kaby lake compatible that's almost pointless. I don't know of anyone who upgrades every cycle. Unless specifically going from an i3 to an i5/i7 or an i5 to i7 (even less likely) already, simply swapping out an i7 for an i7 one release newer is pointless. Very few people would upgrade from a 4770k to a 4790k or similarly from sandy to ivy just to say they did. No valid reason or benefit to doing so.

There will always be a 'newest thing' available on an ongoing basis. Companies (typically) don't just release a product and say ok, that's it, last one ever we're set. Unless someone simply can't live without a feature or has professional...

If you are on a budget, 4790k work fine.

If it only costs you $10 more, then why not (assuming returning everything won't be too much of a hassle). They are almost identical in performance as far as I've seen, but if you can get the newer one for just $10 more then go for it. If I misunderstood and it costs $100 more, then it is up to you, depending on your budget. I have the 4790K, and it works fine, although I haven't done any stress tests or very intensive tasks, I have to admit.

Well I don't really want an M.2 SSD, and speed is really dependent on the memory you buy. DDR4 10 bucks more expensive than the DDR3 I bought did have higher clock speed, but the CAS latency bottlenecked it, making it a little slower than the DDR3. So other than that is there any other reason I should consider Skylake over Haswell? Also note that I'll probably do a future build using either a Kaby Lake or Cannon Lake 6 core (or maybe 8 core) CPU, and I would have to go through the hassle of returning my motherboard, CPU, and RAM

It costs 90 dollars more currently, 100 dollars more when it's on a normal sale (today it's pretty cheap for some reason), and 110 dollars more usually.

Unless someone simply can't live without a feature or has professional needs (and even then it's debatable whether the payoff of upgrading so soon is worth it), intel cpu's have been keeping up rather well for 4-5yrs duration. That was true of sandy, ivy, haswell and now skylake.

16gb of ram is a good starting point for editing, few people are really using 32gb on a regular basis. Another thing to consider, obviously budget may change down the road and so may pricing of hardware. However it was mentioned that the 2011v3 motherboards are too expensive. Many decent 2011v3 boards can be had for $250 or less while many z170 are running $150 or a little less so roughly $100 difference. 64gb of ddr4 will run between $400-500 at the moment (4x16gb). If $100 is 'wayyy' too pricey then certainly so is 64gb of ram. Just trying to put things into perspective.

What will Kaby Lake bring that Skylake won't? Will it be kind of like Haswell-E?

And since speed in MHz is better than lower CAS latency, how high do you think I can overclock RAM that's 1600 MHz CAS 9, 16 GB, and has a pretty good heatspreader (the RAM is mushkin's ECO2)

Only if the motherboard support DDR3L.
