Google is probably the highest paying large software company at the moment. Their base pay is very much above market at the moment due to its recent across the board 35ish% raises. It will be interesting to see how large companies like Microsoft will respond when their recruiting numbers drop.

Your master's degree does not have much of an impact, but I know personally of strong performers at Google with 3-4 years of experience who are receiving 135k-150k in base salary + other goodies such as their obscene bonus scheme and stock grants.

100K$ base + stock options (Annualized) / bonuses 15~10k $ = 115k $ per year pre tax. if you are really experienced add another 10~15k to your base and same to your stock + bonuses = 135 ~ 145 k$ per year.

if you are a star dev, you can always try your luck on wall street firm, D. E. Shaw., Knight Capital and such.
