I was just wondering how difficult it is too upgrade the processor on an imac g5 core 2 duo. Would I be able to do it myself? At the moment it has an intel 2Ghz processor and I want to upgrade it to a 3Ghz processor. This is the processor I'm planning to get Intel Core i3 540 3.06GHz Processor with 4MB L3 Cache on eBay (end time 17-Dec-10 12:04:29 GMT)
