What's the intended use? I assume gaming.... but is it strictly gaming?
Mainly gaming, but also 3D modeling.
An i7-7700K is the "best" gaming CPU right now, but CoffeeLake launches in a couple of weeks, and will offer more cores/threads and, worst-case, should impact pricing (positively) of the KabyLake offerings.
Is there any reason to pick the 7700k over that one other than time preference?
Also I didn't quite understand this sentence as english isn't my first language: "and, worst-case, should impact pricing (positively) of the KabyLake offerings."
Ryzen is another potential to consider, with the increased core/thread count - if you intend to stream etc too, could be beneficial.
Not planning on it so not a priority at all.
Otherwise, that's a very nice setup..... assuming you'll be playing at 1440p 100+Hz or 4K.... otherwise, the 1080TI might be a little overkill (not a bad thing necessarily).
I picked the 1080 ti specifically because I'm going to be playing at 4K.
Which "Supernova"? G2, G3, P2, T2 etc are all great..... the NEX sub line-up though, not so much.
G2 I was thinking of.
For cooling, it really depends on your intended uses. If you're not looking to OC, or only OC modestly, even something "budget"(ish) like an H7 from Cryorig will do the job.
If you want to push substantial OC's (or just have "better" cooling overall), a 240mm+ AIO, or a beefy air cooler like a Noctua NH-D15 would be very good options.
I'm not sure whether I will, but ok thanks.
