Hi! I'm currently running a hack with OS X 10.6.8 with the following specs: Q6600 OC'd @ 3.2 Ghz 4gb of RAM (also OC'd, but can't remember the speed off hand) nVidia 8800 GS 384 mb I'm a heavy Aperture 3 and Photoshop user, not much of a gamer aside from SC2, which runs fine currently. Aperture however slows down quite a bit when processing images and working at 100%. Using brushes can be almost unbearable, especially when many adjustments have been done to the image. Time for a new bigger (and IPS) monitor as well, so I'm looking at a refurbished 2010 27" iMac, with the quad-core 2.93 Ghz i7, 12 gb of ram, and the 1 gb ATI graphics card. But before I pull the trigger, I just want to make sure that this is a worthwhile upgrade. Haven't followed much of the i5/i7 progress. I know it's a couple generations ahead of the Q6600, so this should be a substantial performance increase, yes? Aperture should run essentially flawlessly, correct? (Original Canon 5D files). Curious to hear from anybody who has taken a similar upgrade path and those who use Aperture on an iMac. Thanks!
