While the Oculus Rift is running, there is a large amount of data that is consistently sent back and forth between the headset, positional tracker, navigational controls, and your computer. For those reasons a hefty PC (Personal Computer) is required to be able to run the software as it was intended to be used.
The PC minimum requirements for use with the Rift are as follows.
NVIDIA GTX 970 / AMD 290 equivalent or greater
Intel i5-4590 equivalent or greater
Compatible HDMI 1.3 video output
2x USB 3.0 ports
Windows 7 SP1 or newer
If you are not familiar with what those hardware specifications are you can run a simple test to ensure your PC is “Rift Ready”. The Rift Ready test software that can be found here.
If you are not tech savvy enough to build or upgrade your own PC, Business Wire’s article “Dell Launches More Virtual Reality PC Configurations” describes Dell computer manufacturer’s announcement with their commitment to virtual reality. They are making Rift Ready PC’s that come bundled with an Oculus Rift starting at $1500. The added benefit to this option is the fact that these bundles come with an Oculus Rift despite the fact that stand alone Oculus Rift units sold out minutes after they were available for pre-order. You can purchase these on both BestBuy’s and Amazon’s website.
