Which graphics card should I own for this to run fluently?

[ErfolgreichCharismatisch]

I get the dreaded out of memory error for cuda. I limited the amount of pictures to 40, resolution to 320 x 240 and I still get it.

I am running a Geforce GTX 960 with 2048 MB Dedicated Video Memory.

Can I make it run on this GPU or which graphics card should I own for this to run fluently?

The more memory pn the gfx card the better. at this moment nvidia 40xx series has launched and you can get the 3090 for a nice price, and it got 24gb memory. Im running this card easily, and with just 20 pictures Im quickly up to 10gb on the card.
