Both Intel & AMD have been producing dual core CPU's for a few years now. By default, Windows Vista will only use a single core during boot-up. You can easily change this from the System Configuration utility:
1. In Vista's Start Search type msconfig & hit the [Enter] key on your keyboard
2. Once System Configuration has started, select the Boot tab and click the Advanced Options button
3. Check the Number of processors check box, and choose 2 for the number of processors
4. Click OK twice.
In my testing this reduced my boot-up time around 5 seconds.
