1. Higher clocked RAM is nice, and if it works in the budget, then absolutely - go for it.
That being said, the price difference between the 2400MHz kit I used, and the 3200MHz by CV is $35. IMO, there's just not ~40% improvements to justify the difference in price.
2. A H7 may well do the job, but it's also not available in Canada..... Cryorig will send you one (I asked), but it ends up costing around $100 after shipping. I like the NH-D15, it's a great cooler - even if the OP doesn't OC, or not substantially - the NH-D15 will still keep the CPU cooler than most other air options (admittedly, a degree or two different isn't a huge deal at all). You could get by with a $20-$30 212EVO also, but it kind of loses any real balance in the system. High end components throughout.....and a budget cooler.
3. Your comment on the board, doesn't really match your comment on the cooler - although my pairing was guilty of the reverse. The ASRock board is fine (especially for the price) and will allow some decent overclocking with it's power delivery. Not going to break any records by any means..... but if you suggest pairing it with something like an H5/H7, then you wouldn't be breaking records there either. Likewise, if you go for the NH-D15 (and plan to OC substantially), a slightly better board would never be a bad idea.
4. 4K (depending on the title) can be more demanding on the CPU, with the i7 showing performance gains of varying degrees depending on the title. Worst case, they perform identical - best case, the i7 comes out ahead (especially in min FPS).
If the OP sticks to 1080 or 1440p, then the i5 is more than adequate (that should've been a 6600K in my 1440p recommendation), but at 4K - the i7 is a smart move.
No offence, not looking to get into an argument here - but if you couldn't access PCPP, then you kind of missed a lot of the Canadian pricing 'quirks'. That build (or general idea) looks great, and would actually be great value for money in the US, but a little less so in Canada. Some of the suggestions (MX300) actually is cheaper.... and the Gigabye board is negligible.
Even taking the cheapest of your suggestions, it comes in at over $2,000 CAD before a monitor (and even a 1080p G-Sync monitor is going to cost ~$500 CAD). Now sure, that just about works in the OP's budget, but it's kind of a waste IMO (and would then have them running a GTX 1080 at 1080p w/G-Sync....
I'd be inclined to recommend an i5-6600K paired with a 1070 and a nice 1080p monitor.
No need to spend any more than $1,900 or so. And a great setup.
