Best PCs for running Premiere 2019

Hi all,

I work for a video production company and our owner has offered to purchase me a new machine for editing as we build our new studio. We aren't producing feature length films or anything but we do have 4K projects that bog down my current machine (which was never intended to be a full-time editing PC but my editing role has expanded in the company). With an eye on the future I only see larger projects and more 4K projects coming down the line so I would like to be prepared with a machine to handle them. I'm not sure what budget she has in mind yet but I wouldn't want to go in with too big of an ask, we don't need anything super high end anyway, but we are a professional production company so I can't cheap out on our systems either. Just wondering if anyone has any pointers on particular PCs and what specs would be good for my needs. Happy to answer any Qs to narrow down what would be best for me! Thanks in advance friends!
