Should I retake the GRE to raise my Quant score?

[commtech]

I took the GRE yesterday, and my unofficial scores given at the end of the test were: 160-Q and 168-V. I am planning to apply to Communications PhD programs this Fall (for Fall 2014 entry). I have a 3.97 GPA from my Master's degree. I know the Verbal score is solid, but I just don't know what kinds of Quant scores are considering acceptable for that kind of program... I wanted to get at least 162 in Quant, so I am unsure as to whether to take it again. Any thoughts?

It seems to me that that should be more than fine, especially given the nice GPA plus MA.  If you're into quantitative methods/research, though, I'm not sure.  I'm applying to Comm. programs with 163V/161Q, but I'm not a quantitative person.
