I want to buy a new macbook pro. I am thinking of getting the non retina model of macbook pro as I wont be doing any photo or video editing jobs and don't need a retina display on a 13 inch screen. I wont be playing any games on it as i have a pc and a ps4. But i am worried about the old 3rd gen hardware the regular macbook has. Is it still worthy enough for today's applications and usage?
