I am a new member at MacRumors and am really excited to join the family after being a Windows/Android user. I will be purchasing a MacBook Pro today and am torn on which one is right for me. I am a student studying Computer Information Systems/Business and will be using it for the classes. (Java/C programming, web development, web design, adobe apps, and other applications that a CIS major might use). I am also a DJ and plan to learn audio production with Ableton or Logic so would like the laptop to be able to handle that. Here are two options: Option 1 $1,999.00 13-inch MacBook Pro with Retina display 3.0GHz Dual-core Intel Core i7, Turbo Boost up to 3.5GHz 16GB 1600MHz DDR3L SDRAM 256GB PCIe-based flash storage Option 2 $2,299.00 15-inch MacBook Pro with Retina display 2.8GHz Quad-core Intel Core i7, Turbo Boost up to 4.0GHz 16GB 1600MHz DDR3L SDRAM 256GB PCIe-based Flash Storage The big concern/difference is dual core vs quad core and dedicated graphics on 15" inch. I know it will greatly improve performance, especially in photoshop applications, but since I am just a beginner and most likely will not do any heavy photo editing just web design and development, is dedicated graphics necessary? What about quad core? Can I still easily DJ/make music or design without worrying computer will freeze? I will also be traveling to classes as well as work (DJing) and portability is important. But if 15" power/performance is very important, it will outweigh portability factor. I have 27" samsung monitor at home that I can connect, so screen real state will not be a problem at home. But my monitor highest resolution is 1920 by 1200. Is it too low for design work and especially since Macbooks have much greater resolution? Will it be a waste of retina displays? The price difference is around $350. Should I buy 15" version and be confident that I got a good buy or should I buy 13" version which will be hopefully enough for the beginner/intermediate work, and then upgrade later when Broadwell Macbooks are released? Thank you ahead of time for taking your time helping me choose the right laptop!
