Does graphic card really matter for only video playback?

[Ihatemyself]

I wanted to know if graphic card matters for only video playback?
I want to buy a full HD laptop with a good battery life. Sony EB26 is full HD but battery sucks. I dont want to play any games.Just want HD playback to be the best!!

graphic card does matter for video playback . But these days any gpu should be able to handle HD videos with ease.
