I am sick of my 2009 iMac freezing in the middle of work and just being slow in general with large files, so I am looking into a new one. I typically use: Photoshop (often juggling several 2GB+ files at once) ZBrush Maya Unity 3D Ableton Live Reason Then of course I also have Safari, iTunes and a couple other random apps running. My current iMac is Late 09, 2.66GHz i5, 12GB DDR3, Radeon 4850 512 MB with an SSD. Even when I'm using Photoshop alone I can sense it slowing down. It crashes nearly every day. Maya can be a disaster. What configuration would be required to run the above apps simultaneously and quickly? Rarely would I have them all open at once, but if I'm going to upgrade I want it to be worthwhile. I'm willing to wait til the next refresh but I'd rather not. Thanks in advance for any help!
