The Core 2 Duo is Intel's newest processor, and can be found in both PCs and new Macs. While not technically a "dual processor," each Core 2 Duo has a pair of processing cores in it. This helps optimize performance for things like gaming, video and image processing, and so on. It's also extremely useful for running many programs at once, without sacrificing any of your system's performance. Laptops with Core Duo processors tend to be more energy-efficient and thinner than ones without them.Click here to read more about the Core 2 Duo from Intel.
