Are you sure your wife's computer is free of spyware, viruses and worms? because a 2500+ is not too bad for the usage you described there, although the onboard video leaves a lot to be desired.
If in doubt, hit Antisource.com and there's free online virus scanners linked on the left side of the page, and try Microsoft AntiSpyware beta too. While you'd probably notice the spyware/adware problem, there are worms and Trojans that will not show any visible symptoms.
