I have decided to buy a new iMac just not sure which one yet. The main reason I am getting this iMac is for iLife. I will also do light life Office work and internet and email. I have a 19" LCD that I like and use now so I'm thinking that I should have plenty of screen space with the iMac and this LCD. My only concern is with the video card in the 2.0GHz I don't play games but will the video card hold me back when using iMovie? Also I have heard that the LCD on the 24" iMacs are better then the 20" is that true?
