I want to get a card that I can SLI, but I want to buy just one right now that would give me more then my two cards do now. I have about 300-350 to spend and I want to keep it in the nvidia family and I would like about 4GB of Vram. I have been looking around, but I don't know what the differences are between the 900 series. I play games like Fifa 16 (PC), GTA 5, Fallout 4 when it drops, BF 4, Heroes of the storm, and that is all for now. I would like a card that can run GTA 5 on ultra all settings 1080p and if I get another one I'm sure I will be able to handle whatever Fallout 4 throws at me. For now though is there a single card in my price range with the specs I want that would really allow me to run GTA 5 on all ultra? Thanks in advance.
