Advice on Upgrading a Computer to an Nvidia RTX 3090?

Well, I’ll certainly have to take your results into consideration but from what samplitude and Anarchae1 described, it sounds like a 3090 would considerably up my HP Reverb G2 experience. I’m not into flying airliners and takeoffs and landings but more spawned-in-the-air VFR scenery gawking out in the country in the daytime in cloudless skies going slow, straight, and level in something like a ZLIN Shock Ultra or an Icon A5. With an RTX 2070S and an Icon A5 or ZLIN Shock Ultra, I easily hit 45 to 55 fps of very smooth flying in 2D at ~ULTRA settings. My problem is 8 Gb of VRAM is nowhere near enough for VR with the G2 and I’m hoping, based on the description of others and how much of their VRAM is being consumed, that the 24 Gb of a 3090 will solve that problem, which arises because of the double stereoscopic image and the resolution of the G2.
