What to expect going from dedicated graphics to integrated?

Hey guys,

So, I've currently got an ASUS G73 gaming laptop with A Nvidia GTX460M graphics card. It's a solid gaming computer, I run Battlefield 3 on it. Anyway, I'm planning to sell it so I can get an Ideapad Yoga 13. I thought I would use my laptop for gaming, but no I really just use my Xbox. So, will HD movies and other laptop graphics uses be drastically altered by going to an Intel HD 4000 (which I've been reading good things about)
