Hi Ron.

Yes, memory is a big consideration, especially depending on the software being used but you're not gonna believe this :)

I just notice this comment as I was a doing a test. I've got a GT 710, which is about as basic a card as you can get. It only has 2GB of RAM and costs about 30, I've got it for system testing with stuff that doesn't have an iGPU.

I'm doing the same test again with this card, 9 minute UHD/25 HQX, although only to H.264 as I don't think it can do H.265. It actually works :) So far it's encoding faster, just about, than the i9 QSV was for H.265.

This particular card was always supposed to be none NVENC, I think it was disabled in the driver. There used to be a workaround to enable NVENC but this one just worked without altering the registry.

It may be the case that a system can be built with a very modest card.

Cheers, Dave.
