Hello, I realise this forum isn't really about hardware, but I have a specific question about how the hardware works with Aperture 3 and it's hard to get good answers from the regular hardware sections for this. Currently I am on a 1st gen Intel iMac (2ghz, core duo, not c2d!) with the ati 1600. The ATI card has massive problems with Aperture 3 and Snow Leopard, and I also find Aperture 3 very unresponsive besides, so it has become all but unusable. So, I am looking for a new computer to primarily make my interactions with Aperture less painful. Please list which computer you have, which processor it has and which graphics card and let me know how "snappy" you find Aperture to be. I know that this is subjective, but for reference, when I am working with a K7 raw file (which is 14.5 mp), I generally have to wait a few seconds or even up to 30 seconds to see the changes after making an adjustment. (Faster adjustments are exposure, slower ones are sharpening etc). I am considering buying a Mac Mini, so I can avoid the glossy iMacs, but I am concerned that the 9400m is not up to the task of making Aperture snappy. (Actually, does an iMac i5 or i7 make Aperture snappy?) My secondary usage is to stitch together large mosaics using PTGui (I have a pano head.) PTGui uses primarily disk cache (at least on my computer it does, it goes to disk cache seemingly before filling up available physical memory.) So any user opinions on performance for PTGui would be appreciated too. Anyways, any help is much appreciated.
