That depends on the application: Photoshop doesn't make very good use of the GPU (yet?), so you won't see any difference. CS4 accelerated only zooming, panning and rotation to my knowledge, CS5 adds a few more, but nothing substantial. Lightroom doesn't use the GPU at all.a question for photographers editing and viewing photos with an nvidia 320m graphics card:
are you satisfied? or do you wish you got a discrete card?
That depends on the application. The discrete graphics kicks in when certain functions are to be performed. If I were you, I wouldn't worry about it, the 320M is plenty powerful for most users. I would only insist on getting a machine with a beefy gpu if I knew what I'd be using it for.huh. thanks for the info, i really hadn't the slightest idea.
so, when does the discrete graphics kick in on the 15" mbp? just when playing games, mainly?
