Please Help! - Should I Retake?

I really want to be evaluated properly so let me give you some more info:

In reponse to your questions:

I am a male, Korean Citizen with a permanent resident Visa. English is my second language. In terms of interesting extra-curricular activities, I plan to do some work for NPO's and do volunteer work early this year (not because of my GMAT apps). Keep in mind, I am planning to apply for Round 1 in september.

I may have an interesting background in that I have 3+ years of work experience in the Video Game Industry (I don't think there would be many MBAs from this industry) at a major software company. I've been promoted 3 times in 3 years. I've also had internships in banking with Merrill Lynch and Mergers and Acquisitions with 3M Company. My GPA of 3.73 (top 5% of my class) comes from a top 10 undergraduate business school and since I was in the honors program (about 50 out of 2000 students), I had to take much more difficult honors level courses.

In terms of recommendation letters, I think I can find rec letters from people who went to the Harvard, Stanford, MIT, Penn, Northwesterns of the world. I also have a VP in Merrill that is willing to write me a rec letter. I also plan to travel to every single campus I apply to and get an interview with at least 1 faculty member in the MBA schools to really find out what parts of the graduate schools fit with what I have to offer.

I am hoping my essay grade of 6.0 offsets the low verbal score...

------------

On a side note, although I have 4 years of work experience and 5 years of work experience if I count my internships, I just turned 24 years of age. I was planning to apply with the 680 GMAT score and see if I get in and if I get dinged on all five I would improve my GMAT score to above 750 to show significant improvement on my application when I reapply. My goal is to be able to give a SOLID Application to the top schools in terms of work experience, extra curricular activities, resume, rec letters and of course GMAT. Now, I may not be a lock at any of the schools with a SOLID App that doesn't include extraordinary features, but I am thinking that if I get into at least one of the schools, I'd be happy.

Given my best quant score and my best verbal score(which was still low considering I was getting 38 - 41 on practice exams), I think I can clear 700 within the next 2 months. But I am thinking if its worth it for me to lose 2 months of prep time for my applications, to raise 20 - 30 points. I know having a 700 or 710 puts you in the average score at the top schools but, if I am planning to travel and research a ton on the schools I am applying to, every month is crucial.

Another big worry is the new format of the exams (I don't know how well I would do on a dry erase board)

Sorry for the long post, but I think I can get better advice from you if you knew as much as possible.

Thanks in advance for your response.
