Looking to upgrade. The new new Mac Pro doesn't seem to suit me at this point. I'd rather wait and see how it does the first year or so. So, my original question. Is it worth it to go from a 2008 2.8 8 core to a 2012 2.4 12 core? This would be primarily used for photoshop, illustrator, indesign. I've also considered looking at an iMac. But, I'm skeptical on the shelf life. My 2008 has been great. But, it seems to bog down on multi-tasking and other large tasks. Just curious if anyone has any real experience between these two models. My biggest fear would be to get the 2012 and feel underwhelmed. I also have a 2013 rMBP that is pretty fast. So, my thought would be that an iMac should fit the bill. I'm just used to being able to drop in RAM, storage and other upgrades. Thanks to any that offer advice.
