Sure don't, least not in desktop land.
Edit: Just get the model number off the case.
Lucky I have the manual here, model number is hp pavilion desktop pc p6-2220 (?)
So i think, looking at images that is definatly the same model although looking into some links from google for spec similarities, most dont mention i3, mine is for sure i3.
If you were asking for my actually personal model number, let me know so I can grab it in the morning.
