You can get a GeForce GTX 1070 for $200 when buying a Vive headset

HTC is still selling its Vive VR headset for $599, which is $200 more than the Oculus Rift. However, if you also need a graphics card and are eyeing up the GeForce GTX 1070, HTC is offering a Vive bundle that comes with a Founders Edition version for $799.
If taking advantage of the bundle, you're basically paying $200 for the GeForce GTX 1070 FE. But should you? That depends on which headset you are in the market for. With the bundle deal in play, pricing is a wash between the two headsets, after factoring in a GeForce GTX 1070.
