I have a question about my Dual Core 2GHz Power Mac G5 (Late 2005). Currently, it's disassembled and I have the choice of installing either a 2GHz CPU board or a 2.3GHz CPU board. The 2.3GHz (native) system has a 1.15GHz frontside system bus while the one in my system is clocked at 1GHz. I was wondering if this impacts CPU compatibility in any way, or if there are any other differences I am unaware of? I'll keep this thread updated as I attempt the CPU replacement.
