That was not the goalpost here. The goalpost was that a "great" VR hardware costs $400, which is not true. Same for a $600 PC for high-end VR and as a bonus: the claim that a 3yo GPU is "kicking butt". All of these are false
The GeForce 1080 Ti came out 3 years ago, and I would definitely argue that it's still a card that's kicking butt.
Granted, the poster that said his 3 yo GPU is kicking butt also said he paid $300 for it, which could mean he has a GTX 1060 or equivalent AMD GPU. A 1060 is definitely powerful enough for VR, as it's performance is only slightly lower than the GTX 1070 that I use for VR.
