Resumo: Product looked in good condition, but when I inserted it into the motherboard and stuff, it doesn't boot up (which happens when a cpu is not connected/has a malfunction)
Resumo: Works like a charm. Didn't get the 840 though. Got the HD840TWFK4DGR, which is the 840t. These are 6 core processors, two cores disabled. When I get a newer mobo with core unlocking features we'll see if the disabled cores are defective or not.
