Hello everyone, I am currently looking into buying a MacPro. My question is should I get a "2 Quad-Core 2.8GHz Intel Xeon" MacPro or a Single Quad-Core? I am a visual designer and I use, Photoshop, Illustrator, Flex Builder, Flash, Skype, Safari, and Mail. I usually have most of those applications open and I was wondering if 2 quad core MacPro would be significantly faster? On a side note, I currently have one of the first Intel Macbook Pros. Thanks!
