Kids Entertainment

Should I replace a better video card for a new laptop if I am planning to buy the laptop purposely for online movie and television program? My friends suggest me to buy a new laptop while I told her I need more entertainment for the children when they are on board. Then he just suggests me to use laptop as mini cinema to play DVD or cartoon for the kids in flight. That would be the best entertainment for them. I do agreed that cartoon could occupied them but just I am not sure is it worth to get a new laptop with good video card just for kid’s entertainment. hmm
