My New Build

[AIRDOGG]

Ok, so I am upgrading my rig and just finalized my purchases. Should have done this before but I want to know if I should cancel anything on my order in case I made a poor decision on anything.
So the only thing I am keeping from my old build is my case and Zotac 980TI. Here is a list of everything I have now.

4k monitor: Acer XB280HK

Tower: Corsair Graphite Series ATX 780T Full Tower

MOBO: MSI Gaming Z170A XPOWER GAMING TITANIUM

CPU: i7-6700K 8M Skylake Quad-Core 4.0 GHz

Samsung 950 pro M.2 512GB PCI-EXPRESS SSD

GPU: Zotac 980TI Extreme AMP in SLI (that's one of the reasons I got the new MOBO, the 2 Zotac's are huge GPU's).

CORSAIR HYDRO SERIES H100i EXTREME LIQUID COOLER.

Memory: G.SKILL TridentZ Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3600

Power Supply: EVGA - SuperNova 1300W G2 ATX

I appreciate any and all feedback.

UPDATE: Here is what its looking like so far:

Build looks good, no major issues that I see. Two minor suggestions

- I don't know if you will benefit from DDR4 3600, you could save money by going with something lower.
- Your PSU doesn't need to be a 1300W, a 1000W will do just fine, even with an overclock.

Here is a suggested build

Thanks, I was really second guessing the PSU, its already delivered and in my hands though.
I should have used the partpicker, could have saved some cash. The only thing that is really an issue right now is I accidentally ordered the Zotac 980TI AMP OMEGA instead of the AM EXTREME. I know its not as OC as the EXTREME and as far as SLI goes the slower card will be the limit. Do you think I should return the card and get the EXTREME? I really don't want to go through the hassle, as far as the looks the cards look identical, I should also mention the AMP OMEGA card has already been delivered. If I want to exchange it it is going to impact the completion date of my build.

They differ by 70 MHz on clock speed, 38 MHz on boost and and 154 MHz on effective memory speed. The difference will be slight. As well, you might be able to overclock the OMEGA to catch up to the EXTREME. You are in the silicon lottery for that.

You make a good point, I thought about that as well but talked myself into thinking it was a bigger issue. I feel better about it now. I should have it all put together this weekend. Really appreciate your help here.
