Hi All, I have a Core 1 Duo iMac 2GHz, and have a quick question about the CPU usage. Because I have two cores, should the CPU usage read a figure out of 200% or does it combine the two cores into 100%? The reason I ask is that even on really CPU-Intensive tasks, like HandBrake, it will hover on about 87% (In Activity Monitor and iStat Pro Widget) but every so often, I notice go above 100% (sometimes it reaches 157%, before going back down again) Is this because the application isn't 'dual-core' optimised? I would like to know because it seems like I'm only ever using 1 core. Thanks for you help guys/gals.
