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?
