I agree with @iliketurtlez, You have a shot at some TX MD's. For example, on T-Tech's PLFSOM statistics page, their average matriculant GPA is 3.76 (your GPA is way above the average ) and average MCAT is 508 which you are not far from.
Entirely depends on what your goals are. If you're trying to matriculate to the best TX programs, you will likely need to retake. If your goal is TX MD or DO, I think it makes sense to apply this cycle. If by January you haven't gotten any love, start studying for retake scheduled for March/April/May. If it was exam day anxiety, make sure you take steps to address this before a retake.
