Do you want one for gaming or for professional work like graphics, 3d modelling, etc ..?
The recommendations for both do change. Since gaming monitors need faster response times & good contrast ratios, hence one uses TN panel-type monitors. Whereas for professional applications, accurate color reproduction takes precedence over response time, which is where IPS / e-IPS panel monitors come into play.
It would be just for gaming; StarCraft 2, Diablo 3 and multi first person shooters. I am not looking to reach MAX settings for I only have a single 5770 at the moment.
