I'm going to assume you only need to run games and are not doing anything demanding in different ways (Autocad, 3D Modeling, etc). If you're just playing games, you don't need an i9 intel processor, save the money and spend it on something like extra storage. Anyway, here's my advice:

Notes:
The 960 Pro M.2 Drive would be for your operating system.
The 850 Evo Drive would be where you could place your games, and since it's an SSD you would have pretty fast load times.
If you're only playing games, you shouldn't need more than 16 gigs of ram.
The high end CPU and graphics card allows you to run AAA games on ultra settings with around 120 - 144 FPS on a 1440p resolution; would be even higher on a 1080p.
This build leaves you about $225 for a mouse and keyboard, which is a decent amount for a high end build such as this. Make sure to invest in good accessories.
Also, if you need to make a cut with this build change the 960 Pro M.2 SSD down from 512 GB to 256, 512 is solely for luxury.
