Hi there,
Very broadly knowing NOTHING else about you

, I'd say top 10 would be tougher... and depending upon the REST of your profile (work experience, leadership, activities/involvement, recommendations, goals, academics etc).... that may shift up or down. The top global b-schools tend to have averages more like 710-730, fyi. You can look up the US News & World report ranking list to scan down average scores of US programs, or you can look up average score at each school's website. Businessweek.com profiles also include scores. Keep in mind that while a strong GMAT is often necessary for admission to a top school, it is not sufficient-- the admissions process is holistic and will be based on everything about you.
Wishing you the best, let us know how else we can help.
