Performance do not matter(only affects speed, but what's the difference between 10 second per image or 5 second per image?), you want as much VRAM as possible, which allows for more complex models and higher output resolution. 2060 12GB has the highest vram for the lowest price as of now.
If you can find a 3060 12GB for a slightly higher price, it would be better value, as it offers higher performance.
AMD has pretty cheap models with 16GB vram but unfortunately, due to AI stuff running on CUDA, getting them to work can be trouble.
If you really knows your stuff, perhaps you could get your hands on some second hand Teslas(Like P40? Did not look too deep into them) which can has low performance but a lot of VRAM. But you'll need to put together some sort of custom cooling solution as they are server cards which is designed to have air forced through them. Also getting them to work can be tricky, like AMD cards.
If you don't care about the resolution, just wanted to mess around and don't want to use online solutions(plenty of them on google colab), you can get it to work with as little as 6GB vram.
