Dual Core Pentium 4? I don't think so?!?

Hey, I'm going to sell my old computer on ebay, but I thought I had a 3GHZ Pentium 4 with HT tech, but when I run systemrequirements lab, it says that I have 2 processors running. It also says this when I select system in the control panel. How should I list the processor on ebay? I know intels first multi core was pentium extreme, which this is not...

hyperthreading makes it look like it has two cores.

 

ooh thanks

 

I had a p4 3 ghz dual core look in task manager to see if there are two windows in performance
