Few words.

Didn't change the CPU.

But did change the CPU cooler. I'm not fond of sleeve bearing fan used in Hyper 212 EVO. Reason why: http://www.gamersnexus.net/guides/779-computer-case-fan-bearing-differences
That being said, picked one of the best CPU air coolers that uses fluid dynamic bearings in it's fans. Also a reason why i picked Be Quiet!: http://www.tomshardware.com/reviews/best-cpu-coolers,4181.html

Switched out the Gigabyte MoBo with MSI MoBo for extra features and nicer color theme.
Extra features include: 2x M.2 SSD slots, 3x PCI-E x16 slots, 4x PCI-E x1 slots, support for 3-way SLI, support for 3-way Crossfire, 1x USB 3.1 Gen2 Type-C port on rear I/O.

Didn't change the RAM.
Note: Install the RAM before you install the CPU cooler. CPU cooler's RAM clearance is up to 40mm while Vengeance LPX is only 33.5mm tall.

But replaced the SSD with SK Hynix SL308 500GB. Reason why: http://www.tomshardware.com/reviews/best-ssds,3891-2.html
If your budget allows, you can go with Samsung 850 EVO 500GB if you like.

To match perfectly with the MSI MoBo's black & red theme, picked MSI GTX 1060 Gaming X 6GB GPU.
Best feature of this GPU has is the Zero Frozr. It means that GPU fans won't turn at all when GPU temp is lower than 60°C.
For eyecandy, GPU has RGB LED MSI logo on it's side and red LEDs around 2nd fan that you can control via MSI Gaming App (e.g you can make the LEDs flash according to the music/sound coming from speakers).

Saw that you picked quite a plain looking case. Decided to give your system a better look, so, replaced the case that has a window from where you can see your case internals. Case also has plenty of fan mounts (120/140mm) for optimal cooling.
Note: case supports up to 165mm tall CPU cooler. Dark Rock Pro 3 is only 163mm tall.

And lastly, system's power plant comes directly from the best PSU OEM, Seasonic. 80+ Gold, semi modular and 550W.
750W PSU is too much for a system of yours. Your GPU uses up to 150W, add the rest of the system at about 200W and system's total wattage would be 350W. And thanks to this, you'll do just fine with 500W range PSU while having plenty of room for CPU and GPU OC (overclock).
Though, if you plan on going with GTX 1070 of GTX 1080, a bigger wattage PSU is needed.

All in all, this PC is a variation of my Skylake build (full specs in my sig).
