I'd honestly have to say the Geforce2 ultra would be best for preformance, and like superwormy said, G450 for using dual monitors. But the T&L Ability of the Geforce2 ultra would have a dramatic impact on preformance. If he's using dual monitors.. you can drop in a Geforce2 Ultra and another PCI Video card for the second monitor.. but I really don't know how that would affect the preformance.. Geforce2 ultra looks like the best card for the price range.. hope that helps.
