I bet everyone was in the position to make this decision 
My previous Graphics card is going back to the manufacturer for a warranty repair, I have lying around my old GeForce256DDR (32MB) and a more recent Radeon7000 (32MB).
I would suspect due to age the Radeon7000 more capable however, given the price difference (£25 to £180 when new) I have some doubts in my mind.
I'm not expecting to play anything modern with these cards but I would like to play Quake III and C&C Generals, which would be best. I would install them both and test but the old NVidia drivers are nasty and I'd rather not install unless it is the better card.
