Go to NVidia's web site and check to see if there are drivers available for that card and your operating system. Also make sure that you have the correct slot on your motherboard (PCI, AGP, PCI-E).
If both of these conditions are met, then you can use the card. However, it's quite an old card and probably not much use for gaming. Depending on your current rig, you might be better off without it.
