To have a headset that doesn't make people sick, 60hz is nowhere near a high enough refresh rate. For something with "reality" in the name 1080p isn't a high enough resolution. The displays are too close to the eye and it's easy to make out individual pixels and more importantly the gaps between them [0]. High pixel density displays are a must.
A 480p game on the Wii is still a playable game. An art style that leans into the low resolution will also look fine. While it might not have looked as good as a PS3 it's still playable.
A VR headset with imprecise orientation sensors and a slow refresh rate will make you sick. Your visual input won't match what your proprioception says about your body's positioning. Even if you manage not to get sick such a system isn't usable for non-trivial durations. A low end VR system is not worth any amount of money because it's not practically usable.
