Mobile graphics are always a bit funny, especially with nvidia's remaning fetish... I would think though that that should definately be enough for Civ, even if not on max. A relatively low resolution and the fact that framerate isnt as vital as it would be on a more reflex-based game should definately mean that it can handle things, since they're meant to be optimizing for a lot less. The Intel GMA is what most devs would aim for when they make something 'laptop compatable', so the fact that its any step above that bodes well.
