The HTC Vive is the Steam VR headset made in collaboration with Valve, the makers of legendary gaming series Half Life. The Vive similarly requires a power gaming PC to operate and has a similar resolution as the Rift. The HTC Vive scored in its Lighthouse room tracking that enables you to move around with the headset on for a more immersive experience. However it costs $200 more than the Oculus Rift.
Computers that don’t meet the Rift and Vive’s recommended specs might still run some VR games. But to get a good VR experience, expect to spend around $1,000 if you’re buying a new desktop and maybe a little less if you buy a headset and PC bundle.
