I'm fairly sure I need to get a new computer for the HTC Vive (I'm on Alienware 17 from 2013). My computer seemed to pass requirements on everything except for my NVidia 860m (Do you think it could still work?). But if I were to get a new pc it'd be for just the Vive. What is the cheapest possible pc that is optimized for the Vive. I want it to be able to run no problem however, no low framerate or low graphics.
