Choosing between 2 gaming builds

Hi guys!

I want to build a gaming computer for playing the new 2015 games in mid/high+ settings, edit some videos and stream to twitch. I have nearly no knowledge about building my own computer and therefore components like motherboard, amount of RAM and PSU confuses me. I have narrowed down my needs and found 2 possible builds. I can either choose my components completely by myself - or buy a set of components from a website (with no possibility to change stuff like motherboard, PSU, GPU and more).

I'm not a US citizen, so i pay more for components, keep that in mind when looking through the 2 builds:

Build 1: The build that i have made:
Case: Fractal Design R5
CPU: Intel Core i7-4790
PSU: Cooler Master G650W Bronze
RAM: HyperX Fury DDR3 1866Mhz 16gb
GPU: MSI Gtz 970 4gb PhysX
SSD: Samsung Evo 850 120 GB
HDD: Western Digital Green 2 tb
Motherboard: Asrock H97 Anniversery
Drive: ASUS DVD-Writer DRW-24F1ST/BLK/G/AS, SATA

Price: 1,515$

Build 2: Premade build
Case: Fractal Design Define R5 Black Pearl
PSU: Cooler Master G750M, 80plus Bronze, 750W Modular PSU
CPU: Intel® LGA1150 Core i7-4790K
Motherboard: ASUS LGA1150 Z97-AR
RAM: HyperX Fury DDR3 1866MHz 16GB KIT Black
GPU: MSI GeForce GTX980 4GB GDDR5 PCI-E CUDA
SSD: Kingston SSDNow V300 240GB 2.5" 7mm OEM
Drive: ASUS DVD-Writer DRW-24F1ST/BLK/G/AS, SATA

(And then i need a HDD, going to buy the WD green 2 tb.)
Price: 1,800$

So we're down to a price difference looking at 285$. As I can see, the main difference is in the GPU and CPU, in favor of the premade build. Question is - is it worth the extra money? My budget were originally 1700$ for a pc with a monitor and keyboard (since I'm on a laptop now). I know there is a difference in performance, but I know nothing about overclocking and didn't intend on doing it (as you can see from my build).

I guess i like the fact that someone has fitted the pieces together because I'm nervous that the components that i picked will not fit each other

In summerary, I think i am going for the premade build if you guys think the performance difference is significant enough, but what do you guys think?

If i put a 980 in my own build, will i need a bigger PSU? I'm unsure how big a PSU i need for the parts. Also how futureproof does my own build look? I know it's hard to tell but your guess i most likely better than mine, but I'm hoping for 2-4 years before i need to change my build too much.

Apart from the above, thanks for the quick answer. I didn't think about upgrading my GPU, lol!

JP7PlaysMC - Oh just saw your build now, yeah it does seem almost the same! Can i ask you if you play any high end games and at what FPS? Just to see if i truly need the 980 over the 970, I would prefer spending the money on a monitor and keyboard instead, to save some bucks - still, it might be worth going for since benchmark sites say its somewhat better than the 970... Jesus, it's a tough choice!

Badboyrog2:
I'm from denmark, buying on a danish website (www.komplett.dk - but it's in danish )
My max budget is 1900 USD when i translate from my currency (100 USD = 665 DKK), but i pay somewhat more compared to US prices for all my components due to import taxes etc.

Well this opens a whole bunch of questions:
1. Is the case as quiet as the Fractal Design? I want a quiet build
2. Isn't the MSI version of the 970 better than EVGA in performance?
3. As i can see, the Asrock z97 gives me the ability to overclock, but wouldn't that be over kill since the CPU can't do that? (if im wrong, whats the difference between z97 and h97?)
4. Do i need the extra CPU cooler because of the case or just in general?
5. What are you thinking about upgrading to a 980 instead of the 970 badboyrog2?
