Virtual reality is finally here, but building a rig that can upload your face to cyberspace isn’t as simple flipping on the kitchen light. Not only do PC gamers have to choose between the Oculus Rift and HTC Vive, but they’ll have to make sure their rigs are powerful enough to play VR games. So to facilitate your journey to virtual reality, we’ve specced out two rigs, one built for a budget and one designed to pump out the pixels.
Before we dive into our builds, here’s a brief explanation of why VR requires so much power: both the Rift and the Vive have two displays — one for each eye. Each of those displays show a resolution of 1080×1200. However, the actual resolution is closer to 1512×1680 for each eye, since VR requires rendering graphics with a “buffer” to correct for lens distortion. Add to that the fact that VR requires 90 frames per second, minimum, and you can see why powerful components are a must.
