I'm going for a low end card that I will upgrade hopefully in about january but what is the difference between 1gb of memory or 2gb. I'm going to be buying a 650ti because i'll be playing older games that are not intensive. The newest game I'll probably play is Battlefield 3. I think they wrecked bf4 and i'm not a cod fan. I will be doing some light video rendering though. Anyways, if someone could explain to me what it does for me, or link a good article about it.
