Been reading up abit on various monitors whenever i've had downtime at work the last week.
I think 27 inch monitors seem a bit too big for 1080p res compared to 23-24" ones (same res, only "stretched" to 27" instead of 23-24"), if i'm going to get a 27 i'd rather wait until some company makes a better 2560x1440 res one, because the current ones with that res seem to be quite bad for gaming.
Might be nice to get a 120hz monitor though, and while i couldn't care less about the 3D part of it, i've read pretty high praise from people using the 120hz for significantly "smoother" gaming (and for general use/surfing and whatnot aswell).
