I am an amateur when it comes to monitors.
Does NOT care for 3D, but care VERY much for the 120hz refresh rate.
All I know its a decent jump from 60hz to a 120hz monitor.
Also I heard IPS/PLS panels weren't really meant for gaming.
Right now I am using a 19inch 1440x900p since I sold both my ASUS ML248H and Samsung 2494HM in the past 5 days.
Games I mostly play are Battlefield 3, Starcraft 2, Diablo 3 Beta, Final Fantasy 14 and WILL be playing Guild Wars 2.
Dell has the U2711 for $645 CDN after discount + coupon code (TODAY ONLY DEAL!!).
Also I heard Dell is really decent with their tech support and warranty service.
I can get the BenQ brand new at around $350 CDN.
The specs of my rig is in my signature.
Urgent advice needed!
