Which laptop to buy for video editing in 2018?

Hi everyone!

I could really use your help in choosing a good laptop for video editing and color grading.

I want a laptop on which I can edit in Premiere Pro CC, After Effects CC and Davinci resolve comfortably. I know a desktop is my best shot but I need something mobile because Im often on the move. Im also not sure should I aim for a lot of RAM memory or a great processor or video card etc. I'll mostly edit HD footage and sometimes 4k. I would also be very thankful if you can specify what kind of processor ( how many cores,threads,ghz), how much RAM ( some people say 16gb is not enough) and what kind of GPU is enough in order to fulfill my needs. My budget is around 1500$ and maybe I can push a little bit more than that if really needed.

Thank you all!
