I am currently considering getting an iMac. I have decided that I will definitely get a refurbished 20" model. I want one of the current models because of the updated processors and the faster frontside bus. I know that the 24" screen quality is better, but my desk space is somewhat small and I can't justify the price difference. I also plan on upgrading the RAM to 4 GB. What I can't decide is whether the faster processor and better graphics card of the 2.66 GHz model is worth the money to me. I don't play games on my current pc, so I don't think the graphics card is that important, but will the older graphics card in the 2.4 GHz model influence the speed of the computer when snow leopard comes around? Is the extra .26 GHz of processing power going to make any difference when using iWork, Safari, iPhoto, and iTunes? I may also use iDVD and iMovie, but whatever I do will be very basic stuff. I want this computer to last me a while, so is the 2.66 GHz model going to last longer than the 2.4 GHz? Currently the refurbished 20" 2.66 GHz model runs for $1300 and the refurbished 20" 2.4 GHz model is $1000. Thanks in advance for your advice.
