I've been waiting for iMac for a while like many others. My current usage is Digital image editing using Lightroom4 + CS6 & occassional slideshow making / video editing with iMovie and Aperture. My current hardware is MBP mid-2010 with 2.4GHZ Core2Duo processor + 8GB RAM + 256GB SSD connected to Dell U23 IPS panel and it works relatively okay but seems to be not fast enough. I want to know if going with 2.3GHz quad-core Intel Core i7 base model would be good choice or not for my purpose ? I will definetly upgrade RAM to 16GB & swap out HDD for 512GB SSD on my own. How easy it is to uprade HDD to SSD + RAM in Macmini 2012 ? Will going from 2.3GHz to 2.6GHz make a difference in terms of performance ?
