Umm, I'm not sure. I haven't seen it for a while because my mom needed it at her house. Its still there and I will get it back. I haven't checked into it either because I wasn't the one who bought it. All I know is, its a 24" Samsung. Anyway, I would want to play games at a mid resolution, to keep a good frame rate.
What's your full system specs? CPU, RAM, PSU...etc
Anyway, if you can bump up your budget a little bit higher and grab HD 6870..it will last with you quite enough to play the upcoming games at medium resolutions.
