Hi, I am planning to buy a new MacBook Pro for my graduate studies overseas. I have been a hardcore gamer and a system builder in the past, so I pretty much understand the essence of purchasing a MacBook Pro is trading the performance for the battery life & portability. However, old habits die hard, I am still struggling on specs. Within my budget range, I have the following options. 1. MacBook Pro 13' (2017) , non-touch bar, 256G, 8G RAM, Iris Pro 640, USB-C x2 2. MacBook Pro 15' (2015) , 256G, 16G RAM, Iris Pro 5200, conventional ports. Main Usage, 1. Microsoft Office 2. Database Software 3. Some coding in Java 4. HD Video playback Would love to have some advice on which one to pick?
