i am not sure if we need that kind of score...doubtful and desimba above seem to know better...
i applied to 6 of the top 10 programs (ranked by no. of publications in last 15 years) and got through just one...but again this may not have anything to do with gre scores...and your scores may be good enuf.
what i feel about a retake is that if you honestly think you can perform better with a resonable amount of effort...it is surely worth a try...for e.g. if ur verbal was screwed because of RC and vocab was pretty much ok...then practise RC a little harder and take gre again...
ppl say verbal score may not be that important for finance, but then, gre math hardly serves to differentiate between ppl and therefore, i think, adcom may not be all that ignorant of our verbal scores. and again why let any loose ends in the application?
bottomline: take a mock gre, analyse ur performance, estimate ur score keeping in mind the time u can spend on practising, if this score is 50-60 points higher, then go for it
