I am buying a laptop for grad school. Should I get a macbook pro with a dedicated GPU? I will be using MS Office, surfing the web, watching hulu, handbrake, latex, maybe Matlab occasionally? Does a dedicated GPU help any of these applications? From reading the internet, it seems like a dedicated GPU is only useful for games and maybe adobe cs5. I have a ps3, so I won't be gaming on my laptop. Thanks for your time.
