I have a PC, Rosewill keyboard and mouse, Hyper X cloud 2 headset, 2 Samsung UHD monitors 3840x2160, SLI Geforce 1080ti
I went a bit extra because I also have the Oculus Rift (Wired) with a 4 sensor setup to achieve 360-degree tracking (I only needed 3 but got the 4th on sale for a really good price)
