I own it. Bought it for myself for my birthday on the first day it was available on Amazon. It's been a glorious few months since then, and now when I go out into the living room and look at games on my AWESOME 60 inch Panasonic plasma, I see the 30/60 frames and it almost gives me a headache.
144Hz + 1440p + GSYNC. All TN panels are not the same, and if you check out reviews of the product, almost everyone is impressed with the quality being far above what you'd expect from TN.
Not saying it's perfect, and surely IPS or a different tech would make it look a bit better, but for my uses it is amazing, and definitely worth the money I dropped on it.
