The main purpose of this computer is gaming, but it will be an all-around entertainment system. I watch movies a lot so I want something is also reliable for that. I don't know much about PSUs so I just picked something that I thought would support 2 GPUs should I find the need to add another GPU in the future. Also, can I put a 970 in and a 980 or am I limited to two identical GPUs? If you guys find a similar build that is much cheaper, I'm all ears! Please let me know what you guys think of these changes and what suggestions you might have.

Why don't you upgrade the PSU and gpu first and see how much close you are to the 970's gaming benchmarks first. How much will you pay to aleve small bottlenecking? (up to 7 fps) Skylake should bring Haswell costs down if you don't get one.

I suggest looking into a liquid cooler. Look for the Cooler Master Nepton series. Also checkout a bigger PSU. Cooler Master Power Supply Calculator says it'll run around 400 Watts. 650 Watts will work totally fine if Cooler Master is right. For SLI to work it has to be the same card number. A 970 and a 980 will not work in SLI. But, for example, an MSI 980 will work in SLI with a EVGA 980. Processor GPU and memory is fine.

Astrot70, what PSU would you recommend? Seems that cooler is significantly more expensive. Do you think the price difference justifies the performance difference between the two coolers?

jbaker, you kind of lost me with your last sentence there. I'm not familiar with Skylake or Haswell. Are those models for the i7?

Edit: Okay, so a quick google search gave me the answer. It seems skylake hasn't been released yet though. Know the projected price?

I'd recommend this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182323

But what you've picked out should handle totally fine with much more power to spare. And from what I've read about the Cooler Master Nipton series and what other users have had to say, yes, the price does justify the performance between the two coolers. Plus liquid cooler keeps your processor cooler and runs much quieter that most heatsinks. But, again, your picked out build would work totally fine as is.
Also, From a quick google you may have to update the BIOS on the motherboard after you receive it for it to work with your processor. Maybe. The BIOS may already be updated when you receive it. If not, you'll have to download the BIOS update and flash it yourself with a flash drive.

Broadwell desktop cpus have not been released yet. (broadwell is the generation after haswell that does not deliver much of a performance gain). I would imagine you would pay a bit more for the broadwell or skylake to be competitive with their Haswell cpu's. Maybe $400 for a low end unlocked broadwell. Rosewell does not have as good of a reputation as XFX. Gold rating means there will be less outlet wattage wasted converting it to clean power for your PC. http://www.newegg.com/Product/Product.aspx?Item=N82E16817207015&cm_re=xfx_power-_-17-207-015-_-Product

Thank you guys for the answers!

I took a look at the GTX 980 and I was pretty impressed with it. Do you guys think spending $200 more is worth for the GTX 980 Strix? I'm worried about the VRAM issues with the GTX 970...

New build:
CPU: i7-4790k 4.0 GHz Quad-Core Processor
CPU Cooler: Cooler Master Nepton Series
Motherboard: ASUS Z97-A ATX LGA1150
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
GPU: ASUS Geforce GTX 980 4GB STRIX
PSU: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply
RAM: Corsair Vengeance Pro

What do you guys think?

Alternative build1:
CPU: i7-4790k 4.0 GHz Quad-Core Processor
CPU Cooler: Cooler Master Nepton Series
Motherboard: MSI Z97-GAMING 5 ATX LGA1150 Motherboard
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
GPU: MSI GeForce GTX 980 4GB Twin Frozr Video Card
PSU: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply
RAM: Corsair Vengeance Pro

Alternative Build 2:
CPU: i7-4790k 4.0 GHz Quad-Core Processor
CPU Cooler: Cooler Master Nepton Series
Motherboard: MSI Z97-GAMING 5 ATX LGA1150 Motherboard
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
GPU: MSI GeForce GTX 970 4GB Twin Frozr Video Card 2-WAY SLI
PSU: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply
RAM: Corsair Vengeance Pro

Do you guys think I'll have sufficient cooling if I decide to go with 2-Way SLI?
