I just got done building a new editing PC as well. I went with AMD this time around, but the Intel processor you have listed will get the job done no issues. I have the exact same graphics card and love it. It's expensive but worth it. If you are even thinking about using Davinci Resolve, you'll need a high end graphics card like this. Davinci uses the GPU on playback and caching video during editing. During export, it's all CPU, so the more cores the better. I didn't see the wattage of your power supply, but be sure not to under size it. Other than that, it looks like you are good to go.
