Congratulations! Thats a wonderful score!
To be honest i am surprised why you think of retaking it, if it is just to satisfy your self esteem, meaning that you normally score well above that score then yes, but if it is about improving your chances of getting into your desired business school then i think you should not. This score is above the any average GMAT score of any elite school that exist! So why to worry about GMAT. I would suggest to concentrate on other parts of the application!
Cannot wait to read your debrief!
