Looks like your choice is between a Radeon 9100 and FX5600. Both will probably be bottlenecked by the bus. You might consider something passively cooled... no noise is a bonus... I know for sure you can find a GF4MX and FX5200 with passive cooling... not sure which Radeons are passively cooled. I'd tend to go with an nVidia card for this person simply because it doesn't appear to me that they have the knowledge to troubleshoot problems with drivers or compatability if they can't research what PCI card to get on their own... and even though ATI's drivers have improved, I still think nVidia is more "plug and play" but there are many who wouldn't agree, or would disagree.
