Hey so I am looking to get a new macbook as mine is giving me some problems (its 2012 Macbook Pro 15 inch 2.3 GHz Intel Core i7, NVIDIA GeForce GT 650M 512 MB and 4 GB ram). I am an undergraduate Architecture/Design student and I mostly use Illustrator, Muse, Photoshop and AutoCAD. And at any instance two or three of these app keep running along with safari and etc. My options currently are a) To buy the new macbook although its inferior in terms of processor etc but is very portable and keep my older macbook around and get it fixed as its still under warranty. b) To buy a Macbook pro 13 inch 3.1GHz Dual-core Intel Core i7,16GB RAM with 512 GB Flash storage and Intel Iris Graphics 6100 and dispose my 15 inch laptop as this turns out to be a little cheaper than the upper end 15 inch macbook pro. c)To get the 15 inch macbook pro 2.5GHz Quad-core Intel Core i7, 16GB Ram with 512 GB Memory, Intel Iris Pro Graphics and NVIDIA GeForce GT 750M with 2GB of GDDR5 memory. Out of these two options I like the second option but my concerns are the screen size and the Graphics. But i don't know if i should be more worried about the processor or the graphic card for the kind of applications I would be using.
