Alright, so I've looked at all of Apple's iMacs, the 21.5 and 27 inch models as well as the previous gen refurbished. I'm just wondering what route is right for me: the avid internet user, flash user, very light video editor, and photographer. I want something fast, but I think even 3.06 works for that. Budget on me is around $1,300, if at all possible, but I could go up to $1,600. I don't care if it's new, used, refurbed.. I know I can get the last gen low end 21.5 inch model for around $900. I am unsure what I could possibly pick up the 27 inch previous for on craigslist. Anyways, what really stumps me are graphics. I want graphics better than I have now (Nvidia 9400M), but I don't know if the ATI or new Nvidia are better for what I'm trying to do? I've been a laptop user all my life, first time I'm considering an iMac. Thanks for your input.
