Component advice for first build (with GTX970 1440p)

[MsImAQuickStudy]

Hello everyone! A while ago I decided I wanted to build my first gaming PC, which began as quite a challenge starting from zero. Now that I've done some more research and tried to follow advice, I managed to create a list of parts I'd like to use! But I still have some more specific questions, and because these are that much more specific I decided to ask them in a new topic.

Overview of what I mean to achieve:

I'm trying to build a gaming PC that can run current games like Witcher 3, GTA V, etc. on high settings on 1080p and will be able to more or less keep up with future games too. If possible, I'll use it for Photoshop as well, but gaming will be the main feature.

I might overclock the GTX970 at some point, so I'd like to keep that in mind too.

My main questions at the moment are:
- Is the PSU a properly efficient option for the current build?
- I'm most clueless about motherboards, and I know I don't need Z97, but what would be a better option instead for non-OC motherboard to match my current needs?
- Is there any component that can be downgraded to cost less?
- As you may have noticed, I have not selected a case yet, because there's such a variety of them and I'm unsure which would be most suitable, so any advice on this is appreciated.
- What would be the best option for Wifi and Bluetooth?

General advice is also welcome!


This is my current list of parts:

One thing to keep in mind: the price where I come from (the Netherlands) for this total list is around €1400. Unfortunately, hardware is more expensive. This is more or less the upper limit of my budget.


Thanks in advance

I would recommend Z170, and R9 390X 8GB. Both of these are better for upgrading and gaming. The R9 390X does better at high resolutions.

I did some research and although I would very much love to upgrade, I'm afraid my budget doesn't cover it. I forgot to include my budget limit in the original post, which I've included now, sorry for confusion. Thank you for the suggestion though, if I can save up I might consider that.

Actually, I meant after a year or two you can get the i7-6700K or upgrade to GTX 980 Ti.
