Hi AG,
Thanks for writing in. I would need to know a lot more about your extracurricular work, work experience and post-MBA goals to give a fuller comment on those schools. Strictly from a GMAT perspective -- your unbalanced score may work against you at those schools. I would say that you may be competitive at UT-Austin, but the others would fall into the "reach" category, based on what you've shared with me.
Hope that was helpful and good luck!
