The 660p drive is perfectly fine, especially since your prices are different that US. It won't be as fast as the 970 Evo but it doesn't cost nearly as much either. It will be faster than the Western Digital drive you chose. 

You put together a fairly high end system, so I tried to respect that with my build. I made some side grades and some upgrades and managed to lower the price a little.
You really should have two forms of storage, one for the C-drive and one for data (documents, videos, etc.) If the C-drive gets corrupted, you can reformat it without losing your data. The U12s may have been OK, but if you want to overclock I know the U14s will be adequate. The Asus Prime A would be a side grade, I think. The G-Skill memory is fine. No difference in use. I upgraded your GPU to the EVGA Ultra. The Ultra is their higher end cards, quiet and with a good heatsink. EVGA is supposed to have some of the best customer service of the GPU manufacturers. I upgraded your case to the Corsair 275R with tempered glass- it wasn't much more. I was conflicted with the PSU. You don't need 650 watts, The BitFenix is equal to the RMx, but is not modular. You're saving some money here. It you want a cheaper system, there are a lot of areas where you can save money, but I tried to maintain the quality of components that you started with.

Here Noctua shows the U12s as having medium overclocking headroom when used on the 8700K.

I believe WD Black NVMe drives are faster than same size Intel 660p.

Since you are only recreational gamer and more adobe ae user, i would suggest to go for more core CPU, IE ryzen 2700x/3700x/3800x. Its for the same price as 8700K and it will be better for threaded use, even 2700x is better than 8700K for that. 

What is the basis for this claim?

See the youtube links in my previous post.
You're absolutely right! Something weird happened. It was priced around the $630's but the price must have changed while I was working with it and I didn't catch it. You had to add it to your cart to see the combo price. I'll have to re-work it.

I can't believe that promotion fizzled out, but maybe something new will come tomorrow. Anyway, here's a nice build with  an upgrade to the 9700K. Seemed like it was worth the extra $26, but if you would rather have the savings, just substitute the 8700K.

This is at the very top of your budget, but it's uncompromised performance, prioritizing rendering first and gaming second.

Didn't see he linked the SN750, thought it was the blue m.2

Nice build, but I would split that Intel up into two 500 GB drives.

The AMD chips can be buggy with Premier Pro and possibly After Effects too. I do think you need a fast NVMe drove (not dramless) for the editing drive so I changed the build. The Intel is for the C-drive.

Also, 2700x really costs 399 CAD?!

I would stick with Intel for Premier Pro.

According to Puget Systems the 2700X has slightly better performance than the i7-8700k, https://www.pugetsystems.com/labs/articles/Premiere-Pro-CC-2018-Core-i7-9700K-i9-9900K-Performance-1254/. https://www.pugetsystems.com/labs/articles/Premiere-Pro-CC-2019-CPU-Roundup-Intel-vs-AMD-vs-Mac-1320/

Awesome, I like the look of that. My question would be about the RAM and why you chose that one. It looks like it's a lot better price for nearly the same performance (3000 vs 3200)... is that why? thanks a lot for putting that together

I didn't know the exact budget, but here is build for your consideration. The Noctua you chose was a bit small for that CPU. The Intel is for the C-drive. The HP is for working with video files. The Blue is for long term storage. Only put your windows and games on the C-drive. If it gets corrupted, you can reformat it without losing any data. If it's too expensive, let me know.

When you buy a matched set, it has actually been tested and certified to work as a full set. If you buy two sets, Corsair will certify that each set works on its own, but won't certify that that they work together. Princess Luna may be theoretically correct, but is it worth the risk to save a few dollars? Sometimes the RAM you buy is the last of a batch. Are you sure that you can find the exact same RAM in 6 months- probably. What about two years-possibly. Four years- probably not. Sometimes RAM off the same factory line made the same day will not work together. Even the same RAM can be made differently depending on what parts are available at the time. There must be a reason that they test the RAM. That why I say get the RAM you think you will need now. Don't hope that you can match it later.  If you want to be fully certain, choose RAM off of these lists- this RAM has been proven to work in your motherboard and is guaranteed to do so:
 
https://www.gskill.com/en/configurator   https://www.crucial.com/usa/en/advisor   https://www.corsair.com/us/en/memoryfinder   2 x16 is theoretically faster than 4 x 8 due to less work for the controller, but its a minor difference even if present.  By leaving some slots open though, it does allow you possibly add more RAM later, but again with the caveats mentioned.   The Aorus Pro is an excellent MB for the 9600K. No need to change that.   By the way, are you in the US?   Oh, I see, Canada!

I'd reccommend Scythe Mugen 5 over U9s, the mugen 5 is basically a U14s, but a good bit cheaper. Also 1660 instead of 1060.
