Im getting a gigabyte gtx770 for my new build and I was wondering how much vram do i really need?
I have a single 1920x1080 120hz benq monitor. I'll be playing games like dayz, skyrim, battlefield 4, rust, the forest, watchdogs and others. How much vram do i need to play these games on a single monitor. I'm guessing 2gb. But what if i had a 120hz, and another 60hz as a second screen. All of these monitors would be 1920x1080 BTW. How much would i need if I had a tri-monitor setup? ( 120hz, 2x60hz....all 1080p 24 inch)
Thanks for the help.
