looking to purchase a new 2016 MBP and on the website they offer 2 models, one with touch bar and one without. The only differences I can see is the non touch bar only has 2 TB ports . Slower ram and only offers integrated graphics.. are these the only differences between the 2 models? Are speeds, cpus and battery the same on both models? Also if I did go with the touch bar , I mainly use FCPX and edit videos for YouTube.(1080p) Would I really benefit from the 2gb graphics card?
