Well I'm satisfied, and I know this system won't hesitate with any game I chuck at it. I don't get the second best anymore. When its time to upgrade I'll get the next equivalent x80 series.
... a 5% benefit for $100? When overclocked, the two chips are basically EXACTLY the same. If you wanted nothing second-best, you should have gone with a 690. As it is, you threw away $100 that could have been surpassed with a mild overclock.
My 670 doesn't drop below 60 FPS, ever, on ultra settings on pretty much any game. (Not counting GW2 because it's badly coded and CPU bound anyways.)
If you're going to ask people what they think of your build, don't get aggressive when they try to save you money and get you better performance.
