The purpose is for gaming. But I took into account that I wanted a computer that would be more future proof than most, indicated by the top notch cpu and gpu. I also got a stick of ram or 8gb so I could add another for 16 later on. Added a high power psu for sli graphic cards later on. I'm not sure how to cut down since I want future proofing.
An i7 will not future proof your build, it will only waste your money.
Cheaper board has everything you need.
2x4gb of ram for dual channel. There is no need for future 16gb.
You only need 2gb vram for 1080p.
Bigger and better quality psu for future SLI.
Better quality case.
