Side notes: The gpu i'm getting will be the GTX 1070 ($379.99) Is the memory and clock speed decrease too much? And am I better off going for the GTX 980 Ti (Assuming there is a price drop)

Thanks in advance!

No the Z170X is a socket 1151 mobo that uses DDR4, where the selected CPU is for an 1150 mobo (DDR3). For your mobo would suggest a 6600K and 2x4GB DDR4 2133. Or if wanting the 4690K and the selected DRAM maybe look at the Asus Z97-A or their Pro Gaming mobo in Z97

Alright, thank you, glad I asked, would have been really upset.

I've changed my i5 4690 to a 6600k, and my Ram: G.SKILL Ripjaws V Series 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) Intel Z170 Platform / Intel X99 Platform Desktop Memory Model F4-2133C15D-8GVR

Good choices, let us know how the rig comes out

Will do

Get DDR4 2666 bus ram.With 2133 bus ram you will be limited in overclocking.
That power supply is also not that good.
You can save some money by getting the Gigabyte Z170X Gaming 3 and buy the Samsung 850EVO 250GB SSD.

Consider this build -

This is $56 less then your initial build. Has a more speedy wifi adapter.
Your case comes with 5 fans preinstalled. The case fan i added is to add to the CPU cooler.
If you will not overclock, get this cpu , this motherboard, this ram, exclude the cpu cooler and the extra case fan. With the saved money you can buy the GTX 1080.
