Hi, I'm going to buy a new Mac, but I need some advice I need a computer for: - Graphic Design (intensive use of Photoshop, Illustrator, Indesign, and sometimes ImageReady, Flash and Dreamweaver) - 3D modeling and rendering, and video editing (I'm just beginning, but I plan to do it professionally in the future) My options are (all Core2Duo): - refurbished iMac 20" (1 GB RAM, 128 MB Video) - customized iMac 20" (2 GB RAM, 256 MB Video) - MacBook Pro 15.4" (2 GB RAM, 256 MB Video) - MacBook Pro 17" (2 GB RAM, 256 MB Video) I dont' have the money for a MacPro and a Display. The refurbished iMac would be much cheaper than the other options (even if I wait for the refurbished MacBooks) but i fear that it might not have enough RAM and Video memory for what I need. I know I can upgrade the RAM later, the problem with the iMac is that it comes with 2x512 MB instead of 1x1 GB. So basically, I have 3 questions: 1- How much difference does it make to have 256 MB of video instead of 128? 2- Is 1 GB RAM and 128 MB Video enough for what I need to do, or not? 3- What would you do?
