    I have been looking online for a new CPU to upgrade my old Celeron PC (new MB, Ram, CPU, etc), and I have come across an Intel E8400 3.0GHz Core 2 Duo but in the description it says 'CONFIDENTIAL'. Does anyone know what this means?

    I'm pretty sure that means it's an engineering sample. Not normally meant to be sold on...

    Would it be safe to buy/use?

    Should be. Might well even be unlocked for easier overclocking...

    Depends on luck. As an ES it will most likely be a lower stepping (revision) than the current E8400s (I believe they are at E0 right now, and when they were first released they were at B0). Each revision irons out any bugs they find, decreases heat output, etc. So if this ES was produced before market release, chances are it'll have some bugs.

    By the way, if you care to overclock and want an E8400, make sure you get one with an E0 stepping, they generally overclock like beasts.
