I've had an Asus flat panel for a couple years and it has been great.
The one you are looking at is a 2ms response time which is exactly what you are looking for on a gaming monitor. 1920x1080 always looks amazing.
It uses LED backlights and a 10 million - 1 contrast ratio so you will have stellar colors.
It is also going to be very bright and easy to read.
Also uses HDMI or DVI for your connection.
All around a great monitor, go for it!
The only one I would suggest over this would be a samsung, but you aren't going to find one in that price bracket.
