2014 is the best year for gaming monitors because manufacturers like Viewsonic, ASUS, AOC, Acer, BenQ, and Phillips will be putting G-Sync chips in select models. G-Sync monitors are expected for Q2 this year, so not too much longer of a wait. However G-Sync does require a GTX 650ti or above. AMD cards will not look at G-Sync as of yet. These monitors will also be packed with the lowest of response times, 1080p/1440p resolutions, and 120Hz+ refresh rates resulting in giving a giant advantage over another in player in an online opponent. I can't wait to play some CS:GO when I get my G-Sync monitor.
Hope this explains more and helps you on your future gaming monitor.
