This is an option.

The problem is, while faster on paper, its not really any faster than my 3090, especially in spots where I need its performance most. It'd be a downgrade.

I could get a second 3090, I guess, and have some redundancy in case one fails. But I'm on an ITX board with 1 slot.

I'd be WAY more interested in a roughly equivalent 9000 series or Battlemage card, but alas, there is none.
