    from completed build Flexible and Powerful!

    Managed to get a clean pull of this processor for $155 on eBay. This processor has just reached EOL so server farms are selling off these processors by the boatload, and they're unlocked so you can OC them on the appropriate motherboard.

    One forewarning though: Because this is essentially a 3960X, even though the Intel ARK says it supports it, it doesn't go all the way up to PCI-E 3.0. You're stuck with PCI-E 2.0 bandwidth even though you have enough lanes. The higher end part, the V2 version of this processor which is the 4960X counterpart with PCI-E 3.0 support, is still an active part according to Intel ARK so prices won't come down on those for another year.

    Also, the more slots you occupy or the denser the RAM you use, the difficulty of OCing goes up exponentially. You will require WAY more Vcore with 8 slots occupied compared to 4 or 2, but be VERY CAREFUL with VTT/IMC voltages and never exceed 1.2V or you will degrade your processor.

    Otherwise, this is a great alternative to a i7 Extreme Edition processor that also supports ECC RAM.
