I am considering two options for my next macbook: Mac Air: - CPU: 1.7GHz dual-core Intel Core i7- Haswell - RAM: 8GB 1600MHz DDR3L - SSD: 256GB - Graphics: Intel HD Graphics 5000 Retina Pro 2013 - CPU: 3.0GHz dual-core Intel Core i7 processor. - RAM: 8GB of 1600MHz DDR3L. - 256GB SSD - Graphics: Intel HD Graphics 4000.. I'm a app/web developer. I prefer the retina display, but that's ok too me to use a non-retina display. What I need your advice on is: Is the HD4000 powerful enough for 2D mobile game development/some slight photoshop? I don't play games on Mac. Thank you very much.
