I could not help notice he is asking about a PCI card.
If it were me, I would consider starting with a new motherboard. PCI cards are getting harder and harder to find. Investing in a PCI card today is probably not a good choice, when you could invest in a new motherboard for about the same money,...well,..maybe a little more money and then you open yourself to a whole new set of selections in the AGP realm.
You do not have to be rich to build a new system, just patient.
