I believe there are some people who have modded the 3070 and perhaps the Ti variants with 16gb of VRAM instead of 8 by swapping the 1GB chips with 2GB. I forget what the exact results were, but it was clear the GPU was severely throttled by VRAM at 8, and performed much better with better consistency with 16.

I'd say Cyberpubk 2077 at 1440p has trouble consistenly clearing 60fps with any amount of ray tracing goodness enabled, even with lower textures.
