I am assuming that's your GMAT Prep score?
I don't know that 800 makes sense - I don't think it will hurt but you may want to cross the 99th percentile/760 barrier if it is pretty easy/straightforward. That gives you a few benefits:
1) 99th percentile to have on the resume/etc
2) Some consulting companies ask about it and have a min score
3) You can get a part time job as a GMAT Tutor/teacher/etc
P.S. 800 does not make a lot of sense as a goal and though i have heard about Stanford and 800 scores, I think it is a rumor and not a golden rule, but I would agree that 800 does bring a big of extra scrutiny just because people don't like perfect things. Just human nature.
P.P.S. Your background checks out for a great score but be careful with practice vs. real test. There is a variance. Just be aware.
When you do take a test, please post back - I am very interested in the final result for my crazy statistical purposes.
