I think you can figure out what I have to work with from this. I get no more than maybe 15 FPS in Half-life 2 on the lowest settings with an inane amount of stuttering and loading times and it often freezes up and crashes even when I'm playing low-tech games like even SimCity 2000 and Rollercoaster Tycoon. It even freezes up when I'm just using Firefox.
I got this 4 years ago and haven't upgraded at all. It is just so discouraging that I have to work with this everyday :(.
