Well, the more vram you have the better. I thought my 6gb card in this new computer was as much as I'd ever need when I bought it back in March -- it was they only one available at the time, the other XPS systems left didn't even have discrete video cards, and I'm retired and on disability now, no need of a big work rig. Not to mention the Windows 7 rig that had just died on me only had a 2gb Nvidia card and I hadn't had any problem running Daz or Poser or other graphics intensive apps on that one, so I figured I was doing great going up from 2 to 6 gigs of vram. Ha! Shows what I know. Along comes AI for just about everybody and now I'm just scraping by on that GTX-1660.
