It should definitely be kept (if it's not a word for word match), since duplicate questions will often have different wording than the original. This allows a question to be found in more ways through search, since the duplicate has a link to the original.
If you typed in the title of your question and the original didn't come up in the search, then it's okay to keep yours around so others can find it and the link to the original. If it's truly an exact duplicate (I've seen word-for-word title matches before) then it can be deleted.
