Blackadder, in my opinion, you have no reason to think about a retake. Your GPA and your scores are really good! And I'm assuming the projects you've done are relevant to your prospective MS programs. Now, as Monochrome has mentioned above, GRE isn't going to make or break your chances as your Quantitative score is above the 90th percentile. If u still feel a little nervous or unconvinced, check out the respective program websites for average GRE scores for those admitted in previous seasons (If they're not available on the website, mail them).
Focus on writing an exceptional SoP, complemented with strong LoR's, and you have a great chance of getting into a top school. Best of luck!
