I didn't understand the difference between TN and IPS but l sure do now, it's a real treat. I also didn't understand how important the color gamut error was either but trust me, l don't need 165fps to kill you in any fps.
honestly, it barely matters outside of pro applications, contrast ratio and viewing angles however do.
my monitor doesn't have a good stand and no way to get a different mount, if i'm even 10 degrees off center, the image is so distorted that you can no longer see in shadows in a game.
i want to get rid of my piece of crap monitor, (syncmaster t240hd) but i refuse to lose resolution, and i refuse to go below 1000 contrast ratio. mix in reviews that go in depth and aren't just the press release are a rarity, and its really hard to find decent monitors... not to mention, dropping 500$ on something sight unseen is difficult for me to do too.
