| The Bottom Line | Intel's Core 2 Duo line marks the end of AMD's run of dominance through the dual-core desktop-processor landscape. Not only are Intel's new chips fast, efficient, and well designed, but they're also aggressively priced and sure to send ripples though the desktop PC industry. If you are buying or building a new computer, we recommend that a Core 2 Duo chip be at its center. | Intel's Core 2 Duo line marks the end of AMD's run of dominance through the dual-core desktop-processor landscape.

If you are buying or building a new computer, we recommend that a Core 2 Duo chip be at its center. | Thanks to an expensive new motherboard requirement, Intel's new Core i7 desktop processors will remain enthusiast and professional-level parts until more affordable complementary hardware comes out later next year. Speed never comes cheap, however, and if you're willing to spend for it now, you'll find yourself in possession of the fastest CPU on the market. | |
