That is a 120hz monitor.
It will make your games feel much smoother than just 60hz monitors...
It has a resolution of 1680x1050 which is decent. It's better than 1920x1080 at 60hz... This is a cheap one, so it's good.
I'm assuming that you are playing more fast paced games than slow paced ones... Probably FPS in the future as well?
Anyhow... This will make your games be much smoother if you set it at 120hz in the control panel..
Please, if you are considering a 120hz monitor, make sure that it's 120hz. Most of the time it isn't. Most 120hz monitors are 60hz monitors advertized as 120hz... This one is REAL 120hz.
It requires a dual link DVI as far as I know (it's a basic DVI cable, no worries. But check from wikipedia to see if you need a new cable. Not all DVI cables are dual link. But no worries, dual link cables are cheap)
If you want better colors instead of smoother gameplay, let me know, I can search something for you...
EDIT: You can't vote on this
Most people just suggest something random instead of tending to YOUR needs, so the votes are a bad way of deciding...
