You absolutely must get an IPS panel. You will thank me if you ever see a side by side comparison between an IPS and TN panel. Dell makes a pretty good consumer grade IPS with a great response time.
For comparison, a typical TN panel is around 60-72% color gamut. And color gamut is basically the cover of this
graph that you get in a monitor. (Which is why some monitors tend towards R/G/B.)
One used at work:
U2312M 82% color gamut 23" 1920x1080
Mine:
U2412M 82% color gamut 24" 1920x1200
Go big or go home versions:
U2713HM 99% color gamut 27" 2560x1440
Why are you gaming on this version:
U3011 99% color gamut 30" 2560x1600
That's a lot of information to throw at you, I know. There are actually a lot of Korean IPS panels you can get super cheap but they don't have the same quality assurance (dead pixels and shit get by) that Dell does, along with the 3 year warranty. I know very little about the foreign panels and can't suggest them because I'm ignorant on the subject.
TLDR; buy a fucking IPS. Probably that U2412M.
And my
build from over the summer. (I got everything on sale so actual price around $1500 and that's a pretty ridiculous set up without going extremely overboard)
