Do you need color accuracy for professional jobs like web design,photography? if you do then you want an IPS panel and those don't come cheap ( Apple cinema display is an IPS panel ) if you don't care and just want something that looks good for movies and games and general web browsing then it really does not matter what you get.
cheapest IPS you can find.

Note: you may need an adapter to connect your computer. If your computer has a mini display port plug on the side you will need this :

Both choices will serve you well. You really only need a IPS panel if you are doing graphic design,photography or making movies for a living.
good luck
