I ran the Steam benchmark last night cause I'm seriously thinking about picking up the HTC Vive and my i7 6700, Radeon R390, SSDs, and 16GB RAM got a score of 7.5 with no frames below 90, and the graph looked to be an average between high and very high. The FPS counter mostly hovered somewhere near 105-110.
I guess I'd have to set it up in my living room and I'm not sure where exactly the room tracking laser things would go but I'm assuming it would work. I told myself, though, that I'd have to sell some of the crap I have laying around (computer parts, laptops, humidifier, etc) before I can purchase it. It would be nice to get it off a sale; I should put an alert on Slickdeals for it now that I think of it.
