Just commenting also,
That depending on what CPU you have, AMD or Intel, you may not have to worry about pins and only AMD processor chips use pins, whereas intel chips use... well... chips! :)
Also, on some chips you can actually break off one or two pins and it will still work, because not all chips are needed all the time,
However I am not recommending if you break a few pins, you carry on using that processor, you should still rpelace it :P
