Test Setup

Overclocking: Dual- vs. Quad-Core CPUs
By
Operating System: Windows Vista Enterprise

We have recently switched to a different version of Windows for our benchmarks. Now, all benchmarks at Tom's Guide are run on Windows Vista Enterprise. While this version is not available in stores, its performance results are identical to Windows Vista Business and Windows Vista Ultimate. However, we were forced to make this switch, since this is the only version that offers an Open License. This License allows us to activate Windows Vista over the Internet repeatedly, without having to make calls to Microsoft's activation hotline each time.

Windows Vista Enterprise
Hardware Configuration

We have updated our testbed system with new components, such as the graphics card, sound card and hard drive, in order to offer our readers results based on a platform that is both current and practical.
