Having the G2 for 9 months now all I can say is that going VR is the biggest step in my computer gaming experience since Doom in 1995.
I would absolutely recommend to go this way.
With your rig you will have to make some compromises in quality but with the recommended oxr70/rr90 setting you will have acceptable framerates. With the actual generation of GPU you will be always GPU-limited, even with an 3090/11900k rig. Everything ultra/100/100 I go down in the 20‘s but with my actual medium-ultra/oxr85/rr100 mix I have solid 35-40 fps.
Anyway, don’t hesitate and go VR now, it’s an complete different world.
