I recently bought a 15 inch base model Retina MBP to use as my primary computer. I want to use bootcamp to install Windows 8 mostly for playing DayZ/WarZ/Planetside 2. The main question I have is what size of a partition should I make? Also any input from people with experience on how well a windows 8 bootcamp runs on rMBPs or with experience playing any of those games through bootcamp would be appreciated.
