I realize these two processors are getting older but I was wondering, can I exchange an I7 3770K into a computer whose motherboard was designed to run the I7 2600? I bought a machine cheap that has no processor in it but the motherboard is socket LGA 1155.In looking around for my best option I gather that the I7 3770 was the last of the socket 1155 processors.Will this be a painless exchange?
