I'm interested in the iMac 27' with Radeon 570x/75x, which is a good card to play even at 2K, right? But I would be fine with 1080P with high fps. How good is it to install and play games in Windows 10 through Bootcamp? I would me buying games through Steam and Origin mainly. Is it possible or is the experience bad? Can you connect the Xbox One controller via Bluetooth and play with the dongle Microsoft sells for PC? Thanks!
