What are the rest of your system specs, including make and model of the PSU? Why do you want to upgrade to the i7?

^ Agree with above poster.
However, you should just be able to swap the CPU and have no issues.
Do you have an overclocking (Z170) motherboard? If not, the i7 6700 is cheaper, comes with its own cooler, draws a lot less power, and though it's clocked a hair slower, it will be unnoticeable. I would recommend an i7 6700 over a 6700K if you don't have an overclocking-enabled motherboard.

600mhz is a fair amount of speed lower, but real world performance, you probably wouldn't notice. I went with the 6700k, because I intend on a Z170 board later, and I got a steal of a deal, on my H170 board.

Turbo is dependent also on CPU load and temperatures, so you may not always get it, at all times. Not sure where your 3800 is coming from. When I bought my 6700k, the price was so close, that it made sense, to make the switch, as I was buying a cooler, regardless. The intel stock cooler is ok, I just don't care much for them.

I decided to look up Skylake's exact turbo behavior:
https://en.wikipedia.org/wiki/List_of_Intel_Core_i7_microprocessors
i7 6700 will turbo to 3.7ghz on 4 cores, 3.8ghz on 3 cores, 3.9ghz on 2 cores, and 4.0ghz on 1 core.
i7 6700K will run 4.0ghz on 4, 3, or 2 cores, and turbo to 4.2ghz on 1 core.
On desktop CPUs, thermals almost never affect turbo behavior. On CPUs that't aren't low-power ("S' or "T"), generally the CPU can maintain max turbo indefinitely if not running the iGPU.
So, you're looking at a 300mhz (8%) improvement under 4-core loads with the 6700K.

Yea, I caught a good deal, when I bought mine. With the current price difference, unless the OP has future plans of a different board, and overclocking, the regular i7 does make sense, for them. I do plan on a Z170 board, at a later date, and repurposing my H170, for another build, or to keep as a backup.

That is not enough info. Need to know your full system specs. In your case, as that is an Asus OEM rig, which graphics card it came with.

Then a new CPU will do nothing for you. You need an actual graphics card. GTX 970 and a tier 1, or 2 , power supply, 550w+, at minimum. You may need to measure how much graphics card length you have available, within your case.
