Thanks to all of your help so far this site has got me pursue my first iMac purchase. So I want to make sure I am getting the best bang for the buck, looking at new and refurb. I cannot afford much more than $2100-2300 after taxes and if refurb iCare. Wanting assistance on the three main processors and if there is a great bit of difference in them - 3.4Ghz, 3.5Ghz or 3.8Ghz. My worry is processors and tech changes so fast I want to be the most current without draining the bank. Suggestions?
