If you want a gaming monitor get one with 120Hz.
Good 60Hz models get around 8-10ms ghosting time, while good 120Hz ones get around 5ms. This means less smudging/blur in isometric games (like torchligh), and shooters.
Here's a random 120Hz display http://www.digitalversus.com/acer-gn245hq-p357_10716_38.html
