Cant afford a new 15" MacBook Pro, so i wonder if its better to purchase a new 2016 Macbook Pro 13 non touch bar base model (1900$ + adapters). Or a used early 2013 Macbook Pro 15 with only HD4000 graphics card, 16gb memory and 512gb ssd (1200$). But are they powerful enough to edit 4k clips in Final Cut without lagging? Im a little skeptical about the old HD4000 graphics in the old 15" compared to the new in the 13", but the 15" has quad core witch makes it better for Final cut? Most of my 4k content is from drones and some home videos (Sony A6500).
