Play a lot of wow. But also play bf4, bioshock and metro games. My current monitor is ok ( http://www.lg.com/us/monitors/lg-E2340V-PN-led-monitor ) but looking for an upgrade. Will I even see a difference by sticking with a 23-24" monitor. Not ready for 1440p yet so I'd like to stick with 1080p res. what displays would I see an increase visually?
Why are you looking to upgrade?
If that monitor works fine, and your budget excludes 1440p and 120hz options then there is no real upgrade happening, its just getting a new monitor.
