before looking at the price...
what slot is available in your expantion bay?
PCI?
PCI Express?
AGP?
If you have PCI slots only, get a video caerd that can fit in the PCI slot (white slot)

If you have an AGP slot (they are colored, blue, red, brown, ect) getg a v-card that fits in AGP slot

New PCs should come with PCI Express. If you have this, get a v-card that supports PCI Express
