i run a BFGtech 7900GT oc model, however that is probably overpowered for what is needed.

for AGP

those 2 wouldn't be bad choices for the dollar. keep in mind more videopower will also draw more power, make sure your power supply delivers adequate power for the cards.

best of luck with your decision.
