Hi, I'm buying a new Macbook pro 15 base model, and I am wondering if the AMD 6490 can adequately handle graphic intensive applications, especially with the high-res matte display upgrade. I work in cartography, and often deal with high-resolution satellite imagery. GIS applications can be graphic intensive at times. Am I better off getting the high end Macbook pro? I don't use my mac for gaming. My biggest concern, after reading up on the 2011 Macbook pros, is whether the AMD 6490 can handle some of my GIS applications on a high resolution screen. I am currently using the 2010 Macbook pro 15 (base model without the screen upgrade), and I've never had any problems. It is my understanding from reading forum topics that the AMD 6490 graphics are not as good at the 256MB nVidia 330M graphics. Your advice is much appreciated. Thank you.
