Advice needed for new PC build

[dmata17]

I am upgrading my PC which currently is running:

i5-3570k
16GB 1866MHz RAM
Asus Sabertooth Z77 motherboard
GTX 660ti.
power supply and hard drives I feel are irrelevant.

What I am looking at purchasing is listed here: https://pcpartpicker.com/list/7yfX3F

Intel Core i7-7700K 4.2GHz Quad-Core Processor
Corsair H100i v2 70.7 CFM Liquid CPU Cooler
Asus STRIX Z270-E GAMING ATX LGA1151 Motherboard
G.Skill Ripjaws V Series 32GB (4 x 8GB) DDR4-3400 Memory
Asus GeForce GTX 1080 8GB STRIX Video Card
Cooler Master Storm Trooper ATX Full Tower Case
EVGA 850W 80+ Gold Certified Fully-Modular ATX Power Supply

The case is the one I am already using. I'm planning on reusing it.

I am just looking for some advice on possible better value for my money and overall ratings of the build. Thanks to all in advance

Nice setup , but a 550w - 650w would be plenty , unless you are going to SLI.

I had SLI in mind hoping that VEGA would intimidate Nvidia in dropping prices if it it truly comparable to the 1080. I would rather not spend another 600 for another video card. I would switch to AMD but I have already invested in a G-Sync monitor.
