I am considering getting my first Mac, and my two options come down to the following: 1) iMac Alu 20" (2.4GHz) refurbished with a 20" ACD dual display setup (~$1900) 2) iMac Alu 24" (2.4GHz) refurbished (~$1550) I plan to max out the RAM to 4GB (OWC or Crucial). I will mainly be using it for everyday stuff such as surfing the web, office applications, and also I use Photoshop quite a bit as well. In the future I plan to edit in FCP to make a DVD for my company. Will both of these setups work fine? If I do work in Photoshop and FCP, my main concern will be color saturation. For this reason, would the dual display (glossy iMac / matte ACD) be ok, or is going from a glossy screen (iMac) to matte screen (ACD) in dual display not the best? What are your thoughts? Is there anything else I should consider?
