Want to upgrade to a PCPartPicker build but...

[Bainsol]

So at first I saw this "Great Gaming Build" at Pc part picker (can't link cause I'm new but its the one around 1000 US, 1300 Canadian)
It's been a few days coming up with the money and the parts seem to keep changing. My budget is around 1400$ Canadian.
I want a build that has a good gtx1070 card that I can play currently at 1080p with plans to upgrade later to a 1440p monitor.

I plan on playing some games like The Witcher 3, GTA V, WoW Legion and hopefully new titles that come out in the future at relatively good fps and resolution. I don't need any peripherals atm but I would be needing something for Wifi as I cannot connect directly and possibly a cheap Windows 10 OS.

My Main question about the PcPartpicker build is why the parts seem to change when going from the US to Canada in country settings and if the "Mini" card on the Canadian side has lower performance than a normal one.
Another big incentive is that a local retailer has a price beat guarantee of 10% on canadian e-tailers and retailers which I hope to take advantage of as it would be be a plus but they don't carry some cards at memoryexpress.com

Thanks a lot, and apologies for the newbiness.

Cant say much for your local situation, but this is the best i could come up with for around 1400 from online canadian retailers:

Note: if you go with the build above I strongly recommend avoiding A-Data SSDs.

Thanks so much for the replies and tips guys. I ended up going with a few cheaper pieces due to my local retailer having them in stock. Unfortunately I saw the post about A-DATA SSD after I had ordered it. I'm still missing 2 pieces and was wondering what you guys would recommend...

So far I have

Memory: Mushkin Blackline 16GB (2 x 8GB) DDR4-2400 Memory
Storage: Adata SP550 480GB 2.5 SATA3 Smi SM2256 Solid State Drive
Video Card: Gigabyte Geforce Gtx 1070 Windforce Video Card
Case: NZXT S340 Glossy Black Steel ATX Mid Tower Case
Power Supply: SeaSonic M12II 520 Bronze EVO Edition 520W ATX12V v2.3 / EPS 12V v2.91 SLI 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

So far with that I've spent around 1000 and really want to keep the budget as low as possible now...

My Question is if the i5-6600k Really is necessary with the parts I currently have and will I regret this A-Data SSD? I was looking into perhaps going with

CPU: Intel Core i5-6500 3.2GHz Quad-Core Processor
Motherboard: Gigabyte GA-B150M-DS3H Micro ATX LGA1151 Motherboard

Was wondering if those 2 pieces would be alright or if the 6600k is really a better investment.

Thanks again!

There is absolutely nothing wrong with adata SSD's, in fact they are one of the best budget options they use quality hynix chips and a custom SM controller. They also have some of the best ssd software programs and are one of the only budget SSD's that include a code for acronis true image if you need it.

Really up to you on the CPU, if you went with 6600k you would need a z170 motherboard to support overclocking. I personally think its worth it because i like to tweak stuff, and the system could possible last a bit longer before needing an upgrade. But in all reality you wouldnt notice any difference between an overclocked 6600k and a 6500 unless you were staring at a FPS counter.
