It would also be crap compared to the i3 and 460 combo.
Look at that review and what cards are pitted against each other. The 630m and 640m in the comparo easily beat the Trinity part. A desktop 460 more powerful than either.
Otherwise, I feel like you should be able to do better than 250gb for $70
Like doubling it for $5.

Depending on her usage, though...think about getting an SSD instead. Does she have a lot of games/videos? If so this isn't a good idea...but if she only plays like two things and has a music collection it might be fine.
