Hey everyone, Thanks for taking the time to look. After reading many threads and posts regarding the new rMPB, I feel the base 15" should be sufficient for me. However, I'm truly clueless when it comes to specs and what's going on behind the scenes and I could use some final opinions or suggestions based upon my needs. I'm a graphic designer and photographer who will be designing for print and web, using programs such as InDesign, Illustrator, Photoshop, Dreamweaver and Lightroom. While I don't game, I occasionally use iMovie to edit tutorial videos for YouTube, however, this workload may increase. I'm currently using a 2010 27" iMac 2.93GHz/8GB/1TB and would like a rMPB that is a improvement from current setup as it will become my main machine. Will I benefit much with a upgrade to the processor or RAM on the base model? Any other opinions or suggestions will be greatly appreciated. Thanks again!
