Hi, I’m not very tech savvy so you may view this as stupid, but I only have a GTX 680 (Founders Edition if that means some big difference) and I have waited so long and bought Deluxe Edition. I have read I will need to buy a new graphics card to get 4 Vram. Is there any possible way to get it to work with my current graphics card? I don’t want to buy a new one.
