RTX 3090 ti or 4080?

For the very second time (!) I have a game exceeding the 8 GB VRAM of my RTX3070 when set at Ultra.

First MSFS, and then Steelrising I just tested. The latter allow me to only set Texture to Medium. I can’t change that to High or Ultra as it goes up at nearly 13GB VRAM needed.
That’s don’t sound good…
Mmmm time to think about when I’ll be able to brainstorm with myself about a future GPU upgrade…
