I will be upgrading my graphics cards to two Nvidia GeForce GTX 970's in SLI soon, and I was wondering if 4GB of video memory is excessive for gaming at 1920x1080 resolution. The newest generation of graphics cards from both AMD and Nvidia were designed to run games on 4K resolution. I only have a 1080p monitor. My two GTX 680's (2GB) in SLI sometimes struggle to run games like Crysis 3 and Battlefield 4 on it's maximum settings and resolutions, which is why I am upgrading. I read on another forum that the maximum VRAM consumption of these two games on max detail @1080p is around 2.5GB, is that true?
