As a PC gaming enthusiast, a significant chunk of my time and money was spent building and upgrading my rig, always in pursuit of a better gaming experience. At some point, I decided to take a look past my three 3D monitors and figure out what the absolute best theoretical gaming setup would be.

If you're having a very high-adrenaline, high-movement experience in virtual reality, and then all of a sudden you're back in your office, that disconnect is pretty notable.
