Unlike virtual reality systems like the Sony PlayStation VR which can be used with any PlayStation 4 system, you need to make sure you have the right Windows PC that can be used with the HTC Vive VR Headset. You can try to build your own high performance gaming PC that tries to meet the specs required by the HTC Vive VR Headset. or you can simply choose any of the HTC Vive ready PC's which have been tested to work with the headset.
Some of these Oculus Ready PC's include the:
Alienware Area 51 a51R2-1766SLV VR Capable
The HTC Vive VR Headset connects to these PC's using one HDMI as well as several USB ports.
