Hello, i was thinking about buying me a macbook, im mostly doing photo editing, website graphics and video editing , but im not sure which one should i pick . I thought Retina one would be best for working away from home, but i came across few older's but still with waranty 17" ones which are i5, 1920x1200 + like twice cheaper, i was thinking that i would buy this 17" since 1200p seems good enough when working away from home, and ill be able to use my 4k monitor when home .
