Hi, I had a iMac 2.8 with 500GB and Ati card. I backed up the whole hard drive via Time Machine, on my external LaCie hard drive. Now I have my new iMac 3.06 with 1TB hard drive and a Nvidia card. I want to format it and copy all my files that I backed up on the LaCie. I think it is possible, but my question is : If I copy all my files from my previous iMac with a different hardware configuration, is that not going to be conflicting with my new iMac and its own configuration ? Driver files, etc... Cheers for your help and advice.
