Just a personal opinion, if the school won't take you with a 720, they probably won't take you with a 750.
i agree with kidderek here, although i don't think that this should be the factor whether to retake or not. for me - the ultimate question should be did you show your best on test day or not. if you feel you were far from your best - why not doing it again. if your performance on test day was good (in your terms...), then i think you shouldn't.
i think pelihu retook his test after a good test. i know from my undergrad studies someone who got on a certain test 96/100 and was 4th in class on that course and retook it because he knew he could get 100/100 (and he eventually did). so it is all up to your level of self-achievement, self-confidence, perfectionism and competitiveness... (all are good qualities in my view if they are not too extreme). you should remember, though, that you can give a bad performance when you retake it...
before i took gmat i've decided on a threshold result for retaking, based on my expectations, needs and self confidence. this is actually a suggestion i'd give to anybody. on test day i performed better than i expected so i didn't have to consider retaking.
so... taking your test or not should be up to you and your personality. 720 is a great score, but maybe a dissapointement to you... i don't know... however, as kidderek claimed - i don't believe that the difference between 720 and 750 will make any difference on adcoms.
anyway.... good luck and congratulations on a great score.
