Debating between better cpu or adding gpu

My daughter currently is using a be2300 based system with onboard 6100 graphics. I am considering either replacing the cpu to a a64 5400 plus, or adding adding a geforce 9400 gpu, keep in mind she is certainly not a gamer, she does schoolwork,watches dvd,and video, and does her zune stuff on it,it works fine for all of that. So in your opinion should i upgrade to a64 5400 and use onboard video, or should i go with geforce 9400 and keep current cpu?

I'd go for the geforce 9400 and memory if you can. I got my PNY 2x2 gb pc6400 for $47.99 at Fry's yesterday, plus you get a $20 rebate. Be sure your motherboard will recognize 4 gigs of memory.

Memory and CPU. A graphics card will do nothing for what she uses it for.

I think the key sentence for me was "keep in mind she is certainly not a gamer, she does schoolwork,watches dvd,and video, and does her zune stuff on it,it works fine for all of that"
Signals to me that it doesn't need a thing done to it.
IMHO, give your daugher a gift card with the same value on it you would spend for a new processor, and I think she would be 1 happy camper.
