ive got the following two units: 2010 cMP: 1x Xeon QC 2.8 ghz 16gb RAM Radeon 5750 1gb 240gb Sata III SSD in pcie card 24" Dell monitor 2011 27" iMac: 1x i5 QC 2.7ghz 16gb RAM Radeon HD 6770M 512mb 1tb HDD My primary use is photoshop to design book covers. I used to play games, but I don't have time anymore with all the personal appearances I've been making lately. I finally got my bachelors degree, and I might think about my masters in the future, but any old Mac can handle that. I could do my writing and book formatting on either. The 27" screen on the iZmac is nice, but I could get up to a 40" screen for the cMP. Which one should I continue to use, and which one should I retire? What questions or situations have I not thought of?
