I wanted to wait for the new MAC pro but it seems they will not be there before March 2010. So I decided to buy a secondhands iMac (2.4 GHz, 4 Gb RAM) as intermediate untill the new Mac pro's arrive. My question is if the above described iMac is suitable to edit AVC-I-100 in FCS and other software like Motion, AE and photoshop? I am especially afraid that the AVC codec requires a more powerfull MAC. Any recommendations/advise and opinions based on own experiences are welcome.
