The only 2.5 Ghz dual-core is the Quad Macintosh. The 2.5 Ghz Mac earlier than the 2.7 was two discrete CPU chips.
""there is various extra costs and updates incured for those of us with 1 year old Apple software (FCP/Motion etc...)""
Not sure what you mean by this? One year old software IS Final Cut Studio (as it was introduced at NAB 2005) If you only have one of the pieces like Final Cut Pro 5 without the Studio, then rush to the Crossgrade deal, as for $99.00 you get the whole thing.
Reason why it might be a very good idea, because Apple is giving you one good chance to catch up before they issue the next Full Package ONLY - upgrade.
