If I didn't already have three 680's to hold me over or the rule every other generation, I would of bought a couple titan's. I just wish intel would come out with a badass CPU so I could upgrade that soon.
Playing at 2560x1600 I rarely go over 2gb, I'm sure BF4 will take advantage of it.. Hope 4gb is enough because I don't plan on new cards until the Titanic or 880.
