With how expensive VR headsets are right now, I don't understand why you would pair it with such a budget friendly GPU in the first place.
For VR to become relevant, it has to be affordable enough for the non-enthusiast to get interested in it, which means budget-minded gamers need to know how much it might cost them to get there.
If VR ever becomes a mainstream thing, you might see headsets going for as low as $100: even entry-level smartphones have most of the technology bits required built-in. Rip out the SoC, RAM, battery, WiFi/3G/4G, SIM, SDCard, touch sensor, etc. and you have plenty of budget left to mold the head mount and optics from. There might even be enough budget for a higher resolution display or a pair of 2" ones instead of splitting a single 5".
