some CPU, Processors?

they look like north bridge and south bridge chips. They are found on all types of boards. They have a good yield for gold , cant remember off the top of my head what it is though. If you are pulling them off expect to have the boards you are taking them from to be down graded by your buyer. That is one part that they like to have left on the boards. I do not recall seeing a price list for them by any buyers here but you may do well selling them as scrap for gold recovery on fleecebay. Refiners will scoop them up.
