I have a brand new, factory sealed, Pentium 4 3.06 Ghz CPU. This processor is Intels fastest chip on the market. Includes Hyper Threading support which makes your computer run like it has two processors. These retail for over $500. I am selling mine for $425 shipped in CONUS. Reason for sale: I won this at the Intel road show and would rather put it toward a new scope of course!
