Just got this monitor as well, ordered from TigerDirect via Amazon for 699 plus Asus Vulcan headset for free lol (1 day after my order they increased the price to 799 booyaa) I guess I'm one of the lucky one.
Back to topic, the monitor is absolutely perfect, build quality is definitely much higher than the Korean catleap. Screen is beautiful, picture quality is stunning, no dead/stuck pixel, no back light bleeding at all. Gaming on it for a couple of hours BF3 and Guild Wars 2 at 2560-1440 resolution is incredible lol. I didn't notice any lag ghosting at all in BF3 which is totally unexpected after reading the TFT review on the monitor. They say this is the best PLS/IPS Quad HD monitor in terms of lag ghosting (beats Viewsonic VP2770, Samsung 850D and 970, Dell U2713HM/2711).
I also did some initial testing on the refresh rate overclocking as well, got it to 65 hz stable and didn't wanna go higher lol I'm afraid of breaking my new toy hehe... not that it matter since it has 3 years warranty/1 year 0 bright pixel guarantee with Asus Rapid Replacement program.
Oh and I decided to cancel my Overlord XOC monitor order too.
Side note: Is it just me or does anyone else have problem maxing out Guild Wars 2 on this monitor with 2 GTX 670 heavily overclocked? My frame rates seem to fluctuate between 40-100 fps with everything set to max in graphics @2560-1440.
