Yes, something better is always just down the road... Until something concrete shows up it is just more rumors. I've found over the years that if you always wait for the next best thing you either can't afford it or it really doesn't work with your setup/reality.
People told me that I shouldn't buy a 144hz, Gsync monitor or with one with a TN pane or 1080p. I did, and for the last 2 years I've been enjoying it. Playing FPS games is awesome on it.
Now that I play other games I decided I wanted either a better monitor or VR. VR is what won.
As far as a better GPU, I will likely pickup a GTX 1080. But, I'm hoping I can stretch it out couple of month because, you know, something better is coming...
I think you're right, and you're doing the right thing. There's always something better. But there's always a point in the master race where you have to jump in. And it seems this past week the VR master race bandwagon has filled to the brim!
