Hey, I have a wall, haha. I mean you only need so many fps and the rest are just extra. With G-sync 80-90 works just fine and probably even lower would probably be okay. It's smooth for me and even if I did have more fps it isn't going to get me more kills, but lower settings will. Which would bring higher fps. I'm good to go now, so a 1080 would give me more fps, but not be of any real use. My PC runs pretty good though and if your PC is any different it maybe something else and not the card.
