RTX 4090 or 4080 for VR Lumen Archviz?

Hello everyone,

I wanted to ask if some of you could provide any information or experiences regarding Nvidias top GPUs.

We want to do VR Presentations and are currently using a mobile solution with a 4080 mobile.

Now we want to upgrade to a stationary PC with either the regular 4080 or even the RTX 4090. Can anyone tell if the difference in performance would be big in VR with lumen?

Thanks in advance.
