3090 and 4090 24gb exists. They have 48gb+ as well but you're looking at exorbitant pricing.

Solo con que tenga más de 12Gb me doy por bien servido tampoco es que busque hacer una película a base de pura ia, estaría interesante, pero pues con algo se empieza 😆🤙
You can buy another 12gb card and split the model between them instead of buying a larger card. I know both Invoke and Automatic1111 can split.
