Just playing the GTAV VR mod (https://github.com/LukeRoss00/gta5-real-mod) is just something else, whilst not perfect (hell it's a mod on an old game!) it's so fucking sick being in a car chase at 160mph weaving through traffic in VR.
Can VR get a lot better in 5 - 10 years, hell yea, but that's like saying you weren't going to buy an Xbox360 because the Xbox OneX will be out in 10 years.
I played NFS The Run just in big screen mode (with a PS4 controller) and it was pretty nice. But other than VRChat and the occasional movie (3D is nice), I don't use the headset at all.
For the GO you could set your resolution to 1440x1440 in the config file so you get less jaggies and then tone the graphics detail right down (unless you do have a beast of a PC), it's basically because it has to render the game twice, which it was never meant to do and you want to be sticking to around 90fps.
I will say again, it's not perfect, but for what it is, and the fact someone managed to do this as a mod, you can't complain.
If you are going to do it, install the following two mods:

It completely changes how alive the world is.
