Used, pulled from an HP Gaming PC I took out of service.
Questions & Comments
I am still using this model. It is a great processor. Mine is going on 4 years. Good pickings for the winner. Remember you has to have a lga 1156 compatible board. This processor was almost 300$ on release.
Just to look out for others, If you do not know what processors can be used to upgrade your system, do some research or seek help from a professional before you actually attempt to upgrade your own or others' systems. Extra time spent doing so will save you wasted time later. :)
