Hello, had some questions between two macbook pro models. I'm looking at the 15 inch models and my main question is weather or not the 512 Video Card would benefit me. I'm not to worried about the processor, only being a 4% increase over the lower model and I would upgrade to a 250gb hard rive anyway. I'm buying it so my school-work is separated from my parents desktop. I will be running windows on it too. Mainly it'll be used for word documents, e-mail, and internet. I am, however, delving back into my photo and video editing days and may start playing some of my old games. How much of a performance increase will I see from 256 to 512mb on a video card? I'm not doing anything with HD, and I'm not too worried about rendering times and such so does it really matter? Thanks for any help, greatly appreciated!
