If you are building such a powerful PC why are you going for a 6600K when you could get a 6700K for just $100 more.

$200 more, but has better processor, better monitor, better PSU, better GPU, better RAM.
You might also want to consider going for an M.2 SSD for ~$60 more with triple the speed.

28" screen isn't too big, 27" screen is perfect size since most are that size in case you want to add another one in the future or if you decide to add a 34" Ultrawide in the future they both have the same height.

Already purchased my PC

Got a 1080 Asus Strix then this is the rest

6600k vs 6700k is a TINY margin of improvement.
M.2s are not that beneficial vs a 2.5 SSD.

That is good. Nice mobo choice, and I'm glad you got the 6700K. Also the monitor is a better choice as well.

6700K vs 6600K isn't a tiny margin of improvement.
6700K is the best gaming processor on the market at the moment. And it also keeps up with workstation processors since it has Hyper threading compared to 6600K having no Hyper threading.
Also, since the release of the new processors it has dropped in price and it has pretty much the same bang for buck as the 6600K give or take 1-3%. For $100 more it is definitely the better processor for this system.

M.2 are beneficial vs a 2.5 SSD. The Write/Read speed is 3x faster. If you are only gaming games will load 2-3x faster, and you won't really see much else improvement since it isn't really noticeable.
But if you do any Video Editing or anything else Workstation related, you will definitely be able to tell the difference.

Read the last bolded part again. Gaming vs work station.
And yes it's a TINY bit of improvement. Clock for clock they are almost identical in games.

Also to answer your question, the 6700k is faster in terms of IPC vs a workstation chip.

for most part, fallout 4 does take advantage if I remember correctly

Very few games do. I will agree to that but the premise of every game. nah.

Not the best way to look at things, but it's like dead even in most games.

yeah, I'd vote i7 but thats cuz I'm a multi tasker even while gaming, which brings up how long has 6 cores/ 12 thread intel processors been out and not even mainstream market yet talk about milking it
