First and foremost, I'm very happy with my current setup. I really haven't cared about DX11 as I don't play any games that use it, but with Civ5 (DX11 supported) coming out at the end of Sept., I'm thinking about picking up a GTX 480. I realize no one has any experience with this game yet, but I'm totally a Civ fanatic and was wondering if it'd be worth it.
