Errrrm, acers have really bad PSU's, I've had an acer and after 3 months my PSU started working so hard and making the laptop so hot, it was noisy and it wasn't a site to behold.  Then, after a year, i start to hear the fan as if it has rocks in it, its clicking and its driving me mad, i hate that thing im gonna sell it to some other loser.  Go for the sony, much much better.

Nope.  Your gonna have to stick with the one it comes with since its on-board.  A regular graphics card will be to big to fit in there and on-board ones shouldnt be removed, therefore its not replaceable.
