It seems as though the new 2.26 Octo has been getting a lot of flack since it's introduction recently and I wanted to know if I should wait even longer than i already have or if i should back pedal and buy a refurb. or quad core to satisfy my needs. You've heard similar stories and i've read similar threads, but this is MY story and this is MY thread. I'm currently using a 2.16 Duo IMac. I'm a photographer so most of my work is in Lightroom and Photoshop and usually at the same time. I deal with large scans 100-200mb each and digital files of 25mb each (the latter more than the former). I plan on using most of Lloyd's theories to maximize speed and performance http://www.macperformanceguide.com/ That being said, he has advised me to look at Octo over Quad but that i should also consider refurb Octo over 2.26 Octo. I really don't want an older Mac. Call me picky or finicky or high maintenance,.. whatever. I like taking advantage of the newest that Apple has to offer. oh yea.. my budget is $4500 but that includes about $1100 from OWC for hard drives and RAM. So,.. What say you?
