So I might be getting a 2015 13' MBP and I want to know what performance is like this will be my first mac its pretty expensive so are they worth it? What does the iris graphics compare to I will be getting the base retina model. Mainly I'll be video editing and rendering in iMovie and ill be playing minecraft and recording it for my YouTube channel, I do know that macs aren't for gaming so. My budget is £1000 so I can't configure it further many thanks.
