Hi all, I'm new to the Mac world. Been a Windows user all my life - till now. Well I chanced upon a 1.8GHz DP G5 computer in my company's trash bin and I also had access to a 2.0GHz DP G5 with a dead mother board. The 1.8GHz computer ran fine but was kind of slow so I decided to upgrade the processor to the 2.0GHz version. After much digging around on the internet on how to remove and install the processor, I decided to do some brain surgery. Surprisingly it worked. Now I'm wondering whether I can up the speed with a 2.3GHz or even a 2.7GHz processor. Any advice if this is possible? The original computer is a Nov 2003 model, model number M9393LL/A A1047, PowerMac7,2.
