The VR One not only gets an upgrade to faster GTX 1070 mobile graphics (on top of an overclocked Core i7 processor), but runs about 50 percent longer than the Computex model at 1.5 hours of VR use. And since there are now dual battery packs, you don’t have to shut down entirely to keep playing. You can hot-swap batteries as much as you like, which is particularly handy if you’re either an avid player or want to share the backpack with others.

MSI hasn’t divulged launch details for the VR One, although it had promised that a back-mounted system would be available by the end of the year. It’s reasonable to say this won’t be cheap given both the higher-end parts and VR-specific requirements, such as those gigantic removable batteries.
