Looks great, I did a very similar upgrade about 1.5years ago, also from 7600K to 5600 (non-x). I kept my Vega64 GPU. Runs smoothly for my needs (some light 3D modeling in Blender and light gaming: The Forest 2, RDR2, even HL: Alyx on the Index runs fine). It was almost 2x as expensive than yours back then, but I also went for an SFF build with a B550i.
