M5 MAX 128GB vs 2x RTX 3090?

I am trying to decide between Mac Studio M5 MAX 128GB vs 2x RTX 3090. I understand that I can run larger models on the M5, but I don't understand what the capability differences would be. Nor have I been able to get a "sense" of how fast the difference would be.

I keep seeing huge advances in the 2x 3090 arena, but I don't know how they translate to the real world.

If my use case includes coding tasks, image recognition, and general hermes type stuff, is there any reason one would be less capable than the other?
