This is going to be used for a lot of different things. Some of them include programming and game development with Unity. Once graphics cards are back in stock, I will also be using this for gaming. I would probably get a gtx 1080. By then I will also get a new monitor, probably a 1440p 144Hz or a cheap 4K 60 Hz. For anyone wondering, the graphics card I'm using right now is temporary, because X299 does not have integrated graphics. The CPU, Motherboard, and SSD I got discounted, so the price you see isn't what I actually paid.
I pushed the CPU to 4.5 GHz with Gigabyte's included tool, and the CPU stayed below 50 degrees under load.
Recently acquired a gtx 960 4GB from a friend for helping them upgrade their system. Also bought a new mouse because my old one stopped working.
