Dual Core (silly) question!

[smartie]

How can I tell if I have a dual core or not?

PC is a 3.0Ghz Intel (R) according to my System settings, and it has Viiv stickers on the box?

Any way to tell?

system says "Pentium (R) D CPU 3.0 GHz

"ACPI Multiprocessor PC" in Device manager under computer??
