2nd Attempt GRE (Do I need to retake it again?)

[A2797]

Hey,

I had taken my GRE for the first time in July when I received a score of 315 (160 Q 155 V 5.5A), i retook it last week and got 323 (164 Q, 159 V)  - I was aiming for 165Q , 160V but fell short by a few marks.

My target program is an MS / PhD in Mechanical Engineering. I am looking at some top schools like UC Berkeley and MIT and I understand my Quants is a bit on the lower side - however my GPA is close to 3.9 and I have 3 research publications and quite a few internships. So will this help offset the scores in any manner? I really dont want to take it again if absolutely necessary. 

Any inputs would be appreciated!
