Buying a new LCD monitor

hay guys

I currently have an Acer AC901 19" which gets very hot (it's summer here in Australia and above my desk are shelves which hold my folders of schoolwork etc so all the heat gets trapped under them) and I'm looking to buy a 19" LCD monitor. Hopefully this won't generate as much heat and might be a little nicer to work with.

I do play a lot of games (especially now that I'm on holidays) so refresh rate is important to me. What's a good number to aim for that won't attract a large price tag?

Can anyone suggest any good monitors (with good warranty) around the AU$300-500 mark?

Thanks!

You want a CRT monitor instead. Half the money, over twice as good, just takes space from where you don't need it.
