Hi, I was wondering if any of you could help me on this. I need to either upgrade my processor (or if I can't I have to buy a new computer) and wanted to know if it's possible to do this on an iMac. In system profiler it says under model identifier that I have an iMac4,1. I'm almost positive that the iMac I have is from the first series of iMacs that used Intel Processors. I need to upgrade from the Intel Core Duo (1.86 Ghz) to an Intel Core 2 Duo (2.5 Ghz) or equivalent. Is this possible to do? Also, as a side question, I need to upgrade the RAM on my machine too. Do I need to buy RAM from Apple directly, or can I just buy something cheap from new egg? Thanks in advance!
