You should be just fine at 144 at 1920x1080 with an 1800X. Just OC it to 4.0 manually to ensure its performing to its full potential. I know it turbos to 4.0 but it actually makes a huge difference forcing it to 4.0 manually. You're looking at a 5-20 FPS increase (at stock clock speeds, no OC) with the 7700K and that difference is like 120FPS from the 1800X and 130 from the 7700K (or 150/160, depends on the game and the scene). There's some great demonstrations of this out on the youtube. Contrary to popular belief, you don't actually require 144FPS to be smooth an a 144Hz display.
On the editing & rendering side the 1800X will smoke the 7700K.
