Do you have a PC that can run VR? That is more important than buying the VR. What are the specs of the PC? Id personally wait until they release a new generation of headsets etc. and make sure your PC is to par for VR. There are not a lot of games at the moment and development is still slow. VR porn is huge though. Lol.
Thanks for the comment and yes my pc is vr ready. Gtx 1060 6 gb and i5 4460
It all depends on the games you are into. There just isnt a whole lot of them out yet. But there are some good games. Here is a list of some good games compiled by tech radar. http://www.techradar.com/news/gaming/15-best-vr-games-best-virtual-reality-games-for-pc-and-mobile-1300576
Personally I would wait for the second generation of development. Those headsets etc arent to far off and would be a better investment. VR is a kind of a luxury gaming item at this point... If that makes sense.. Just be sure there is enough content that you will enjoy now.
