MacBook Pros since at least late 2013 support 4k @ 60hz. That's a seven year old laptop. I've been using 4k displays with mine for years with no issues, both at native and scaled resolutions without taxing the cpu/gpu. I would highly recommend it. Your info might apply to other models but definitely not the last seven years of mbpros.
