Try and work out what matters more, gaming or general use. Whilst i love gaming, i spend more time watching TV/Movies and generally browsing the web or writing code personally, so i'll most likely opt for an IPS screen when i do a build(use to have a 24" DGM IPS years ago before i sold on the system but i'd never go for anything less than an IPS now - if you've never used IPS however you won't likely feel you're missing out on much).
I love gaming(as much as the next guy), but i'm managing right now on a 19" Dell 4:3 screen at the moment(surprising how good quality it is for such an old screen), even in Planetside 2, where i can notice tearing etc... (i've got so use to it though, unless i'm thinking about it, it's a non-issue).. naturally such things may matter more to you.
Work out your priorities and go from there...
