Worth upgrading from 5800X?

(sorry for another AM4 thread)

My PC is 5800X, 32GB DDR4 3200, 3070 8GB.

It handles most games ok but am finding some of the newest/most demanding stuff requires a drop from high settings.

The one that stands out is MSFS2024 which I know is CPU intensive and also wants lots of VRAM. I get the “out of VRAM” message a lot in busy areas/large third party airports and also awful chugging/stuttering when landing at them. Running the AutoFPS app helps a bit.

Don’t really want to replace everything to go AM5, I upgraded from 16GB a month ago and it’s made a difference.

Is it worth the cost of a 5700X3D (currently CAD$389 on AliExpress, 5800X3D is CAD$529 to keep this PC going another two years? What would be a worthwhile GPU upgrade to get 16GB of VRAM?

PSU is 850W so it should handle a newer GPU and I have liquid cooling for the CPU.

Thank you.
