Speaking as someone that just got accepted to a couple of schools, it seems to be the case that the gres are one of the least important aspects of your application.
Here's the gist:
If you have great courses and grades, a great writing sample, a great sop, and great letters of rec, you can get into any 10 program even with mediocre gre scores (75th and above).
That being said, if other parts of your application is mediocre, having a great gre score will probably not get you into a 10 program.
Don't worry about gre scores. Worry about your courses/sop/writing sample/letters
