I will only use it for content creation like Adobe Photoshop, Illustrator, InDesign, Muse and Edge Animate. No video rendering! I was thinking about the base 2.0Ghz 15" Macbook Pro Retina with 256GB SSD og 16GB memory. Right now I have a PC with Sandy Bridge 3.4Ghz, 128GB M4 Crucial, HD4000 only and 8GB memory. Will this be a good upgrade for my Sandy Bridge PC or should I upgrade the CPU with 2,3 or 2,6Ghz? What about the NVIDIA GeForce GT 750M or are Iris Pro good enough for my needs?
