How many FPS should I be getting with these specs?

Yeah 1GB won't cover it, I would get 2GB or 3GB of RAM from a href="http://crucial.com." rel="nofollow"http://crucial.com./a I would only install Battlefield 2 and Counter Strike, if you want online, I would also disable any security software, and end processes with your username on it except of Taskmger.exe and eexplorer.exe.
