That's what I am also wondering too. BF4 is a bit more demanding after playing the open beta. We won't know for sure how Ghosts will run on our rigs until the game is released. I am going to take a wild guess because of it's engine as always. If you look at the release notes of the engines used in the CoD games, you won't see too much of a difference until IW6. http://en.wikipedia.org/wiki/IW_Engine
