You'e going to need to spend about $1,000 on a PC (before monitor) and about twice that amount on a Mac if you want to get into editing raw 4k with any kind of smoothness. And you could easily double both those numbers. And that's for basic UHD 4k. If you plan on using a lot of visual effects, transitions, color coding, stabalizers, or if you see your company doing mapping in the future, then you will need to build an even more robust computer. Unless of course you like sitting around and waiting for rendering and exports all the time.
