Hi AaronEzra,
First off, a 710/Q49 is an outstanding Score, so you can comfortably apply to any Business Schools that interest you. As such, a retest is probably not necessary. Depending on the Schools that you plan to apply to, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/There's no 'harm' in retaking the GMAT (but again, it's probably not necessary - and your time might be better spent working on other aspects of your application). The biggest differences in the Exam options are really in the 'formats' (for example, when you take the GMAT at a Test Facility, you can take the test sections in different a different order, there are 8-minute 'breaks' and you will likely need to wear a face-mask). As such, you might need some time to train for the specifics of that format.
