I find this thread rather surprising. If you research the web, this used to be a popular Mac question: should I buy the dual or the single? The answer used to be that you would see no difference unless you were using one of the few multiple processor aware apps (i.e. Photoshop). Indeed I understand that DP macs were Apples desperate answer to the lack of faster processors from their suppliers. The thing is these are all referring to the days of Classic Mac OS which did not support multiple processors at all. Only when OSX came along did you start to see any widespread benefit. Nowadays everybody has multi-core processors. This is because the designers have given up trying to make them faster. So the future is multiple processing. If you open "Activity Monitor" and select the "cpu history" window it shows you the level of activity for each cpu. I was just watching a video on-line: http://www.guardian.co.uk/travel/2009/sep/09/cycling-tour-of-britain-devon and it maxed out BOTH cpu bars. So I rather fancy that I'd prefer a slower dual than a faster single. Or is "Activity Monitor" lying to me? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
