By today's standards, that card is only suited for web browsing, and even that would likely become annoyingly slow when there's anything 3D going on or video is playing.
Seriously, if you're building a new system but looking the use some of your old components, the 10-year old video card should not be one you're looking to re-use.
If you're not comfortable picking your own components, provide us with a description of what you want to use your computer for, how long you'd like it to do so before you have to replace it again, and a budget on how much you're looking to spend. Also, list all your current hardware, including the monitor. Though, I cannot help but feel that most of your components will not be reusable based on the age of the video card within it.
