I'm looking to upgrade from my G5 isight iMac. In the past, I have done some film work (SD) and was irritated by the slow render times. Though not doing this work now, I may well do some in the future (hobby/ prosumer). So for the new machine, I was looking for the following: - lasts 4 or 5 years - able to edit prosumer HD - quiet - runs OS X Following the disappointing iMac refresh (I think my 4 year old machine has a better firewire capability and screen for example!), I don't think they will do. I was considering a hackintosh/ e-fix solution but am not that inclined to build my own system and want something quiet that doesn't have to worry about breaking compatibility through software updates So having rages against Apple for not delivering what I wanted (brilliant computer that costs sweet FA), I have slowly come to the conclusion that a Mac Pro is the way to go. The 2009 ones seem expensive (especially as I live in the UK). Would it be better going for a 2008 revision, or even an earlier one (ie second-hand), and load it up with RAM etc?
