PC build help as august 2017 - 1200$ budget

Hello , sorry for my bad english.
i’m willing to buy or build a new pc at the start of september for unreal engine and other software (UE , UNITY , After effect , Premiere , Maya , Zbrush) , monitor and mouse are not included in the price so it’s just for the pc.
I’m tryng to handle 3 monitors with this build.

So this is my build for now :

i should be under the 1200$ budget for now and i dont really know what to change or upgrade , also i’m not an expert in pc build i always used laptop and this is my first home pc.
Any advice is accepted also if u think this build is shit please tell me :smiley: , i’m not gonna build the pc by myself but i will ask help to a friend who is more expert then me (i’ve never build a pc with my hands)
Also i dont know if 1200$ is a good budget for a good game developing pc and i should wait more.

**Intel Core i5-7600K
Cooler Master Hyper 212 EVO
GIGABYTE GTX 1080 Windforce OC
Crucial Ballistix Sport LT 8GB(1x8GB)ddr4 (maybe 16 gb it’s better but i dont really know if the pc can handle it)
EVGA SuperNOVA 750 G2
SanDisk SSD PLUS 120GB

Thank you everyone
