Valve mistakenly posted an image and description of the yet to be announced Index VR headset on Steam. Soon the company deleted all the information, but by that time users had already copied and distributed it on social networks.

According to the leak, pre-orders for the Valve Index will open in early May, and full sales of the novelty will start on June 15. The virtual reality helmet will be equipped with built-in headphones, as well as DisplayPort 1.2 and USB 3.0 connectors. The package will include a renamed version of the Steam VR Knuckles controllers – Valve Index Controllers.
For the headset to work properly, you need a computer equipped with 8 GB of RAM and a video card no worse than Nvidia GeForce GTX 970 or AMD Radeon RX 480.
