I've never tried a VR set before, but I am not impressed with the current software either. The only game that Im awaer of, that is 'worth' to play in VR would be Resident Evil 7.
Although alot of people say that traqditional walking in VR would make them motion sick, and therefore they teleport, but this might be just weird.
I'd buy a Playstation VR headset, as my current PC isn't just potent enough, and I highely doubt that an Sandy Bridge CPU/iGPU can run anything VR at all.
