DLSS 3 available in VR yet and graphics card advice?

Many thanks, that’s helpful.
I understand that DLSS 3 can be used to very good effect independent of frame interpolation (that is just the upscaling part without frame insertion).
I guess my hope is to figure out if the newer generation of Nvidia graphics cards (40 series) can offer significant performance boosts in VR with the latest generation of upscaling technology?
