AGP video card

Solution
I doubt the 6800GT will run on a 250W PSU. More so if that PSU is old and has been in use for a long time. A 6600 or x1600 is probably a better call. As mentioned above you might be looking at any AGP card you can find. They aren't very common now.

Solution
There are PCI 5450 and GT 520. They are more recent and is an alternative if you can't find any AGP card.
The AGP 3870 is slightly faster the 4670 but the 3870 is even more rare. I had an APG 3850 before. Best resell value graphic card I have ever owned. Sold it at the same price I bought it for after using it for 3 years.
