Quick question, I was given a PowerMac G5 7, 3. It currently has 2.5 gigs of ram. I'm looking to upgrade to 8 and pop in an SSD, but on OWC, their isn't an option for a 2.5Ghz cpu speed powermac. In my system profiler it says 2.5Ghz Dual Core, but OWC shows a 1.8, 2.0, 2.3 and 2.7 ghz models... not 2.5. So is my system really 2.3 or 2.7?
