Is Lenovo Thinkpad P50 good enough for editing in Premiere Pro?

I can't edit on my macbook pro anymore so I need to upgrade but I'm on a budget... preferably under $1,000, and I'm leaning more towards buying a refurbished laptop. I edit videos a lot, nothing crazy but definitely with transitions and effects and sometimes 4k footage. Has anyone a positive experience editing on the Lenovo Thinkpad P50 or is there a better option within my budget that I should check out? Thanks!
