I'm working with an Intel Core 2 Duo CPU and I have to say that I'm not too impressed by the performance of the computer. The tasks that I have tried so far include: Batch processing camera RAW files to JPEG Cropping and straightening image files Viewing and scrolling through JPEG thumbnails Facebooking and using other Web 2.0 pages The system doesn't feel much faster when viewing bloated Web pages and Facebook applications can bring the Web browser to a Spinning Beachball stall, the rendering of thumbnails is still not instantly-quick until I preprocess and load them all into RAM, and the JPEG file output is the same speed as on a G4 system. The cropping function is actually less responsive than it was on the G4 system. I assume that this is a problem with code optimization, because there's no way that a new Intel CPU can possibly be the same speed as a 6-year-old Motorola CPU. Apple says that the Megahurtz Myth is over now, so I expected that a 2 GHz Intel CPU would outperform a 1.5 GHz G4 CPU. The system doesn't feel hot after several hours of use, so that indicates that the software isn't fully using the CPU. What does make it hot is Adobe Flash, but that's another issue. I wonder if I really do need to buy an Arrandale-based system to finally get better performance. I could blame the software developers for not optimizing their code, or I could get excited about the rumors about the new Arrandale laptops from Apple that should have been released months ago. Rumor watching!
