i understand your feelings man. Imagine my situation - i bought this monitor ahead for my next years rig with Boradwell E + Pascal GPU, still about 5-6 months from now.
I will be able to test g sync only in 6 months time, since right now im running it with my 3 years old laptop with 680m and with DP 1.1 at 50 hz.
Only thing i can say, even now this monitor worth every penny, and i dont care about some barely visible lines that i might or might not notice, and only if specifically looking for it, i will just enjoy this monitor.
there is nothing out there even to be remotely close to this monitor, and to be honest its nearly impossible to find a perfect one anyway, so taking all into consideration, its well worth it.
