Newegg has the AMD Phenom II X4 940 Black Edition Deneb 3.0GHz: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103644
(OEM--no heatsink) for $96 with free shipping. Seems like a good deal for
those with AM2+ motherboards .
NOTE: This is socket AM2+, not AM3.
Seems like a great deal for someone wanting a Phenom quad core, but can't
afford or doesn't need a top of the line model (or someone with an AM2+
board looking for an upgrade).
