Here's a Tech question for you... Does a PowerMac G5 Dual 2.7 have two 2.7GHz processors or two 1.35GHz processors? If it has two 2.7GHz processors, does that mean that it can process at 5.4GHz? If its two 1.35GHz processors I am again slightly confused.. If Apple sell a single 1.8GHz PowerMac, why cant they stick two of them in to a PowerMac to make it a dual 3.6GHz PowerMac? What's holding Apple up with the advances in speed?
