How much space to convert when bootcamping
I have a 128GB 2015 macbook pro 13' retina display that has a 3.1GHz Dual-core Intel Core i7, Turbo Boost up to 3.4GHz and 16GB RAM.
I want to bootcamp my mac to play games on Microsoft however I still want enough space to use the OS X part for my student work.
What do you think would be a wise amount to convert to Microsoft?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
