Tbh. even for quality gaming, I don't see much use in "non-ghosting" and superb latency. All that matters is input lag, and that's that. For the rest, I prefer AH-iPS, PLS, or AMVA+ displays, thanks to superior color accuracy, better and deep blacks and many more.
But when You're some "pro" gamer, and want all of those geeky thingies that a gaming monitor should have and You don't mind getting Your eyes shot by lower quality tech, it's a clear weapon of choice.
