For all models fitting 2x 5090 (2x 32GB) that's not a problem, so you can say if you have this problem then RTX is also not an option.
On apple silicons you can always use MoE models, which work beautifully. On RTX it's kind of waste to be honest to run MoE, you'd be better off running single, whole active model that fills available memory (with enough space for the context).
