I think for gaming (maybe excluding 3-display systems) this new Asus VG278HE is a very good alternative. I bought it and made some input lag measurements. Few links: REVIEW: Asus VG278HE Input lag measurements I'm not using 3D but 144 Hz at 2D and I'm extremely happy with it!
Those 144Hz monitors look pretty cool. It pisses me off that electronics, like alot of other things are so much cheaper in the U.S but yet the Canadian dollar is worth more than theirs. http://www.newegg.com/Product/Product.aspx?Item=N82E16824236313
Sorry I didn't remember that anymore! Oh well at least the review wasn't mentioned before... You have this display and ATI card? If so does it work at 144 Hz with ATI too? I think owner manual said it's only supported by some 3D thing by nVidia. Think I'll have to do input lag measurements for 120 Hz mode too.
