So here are the most recent numbers from MIT(the BIG dog in engineering). As you can see MIT likes to provide a very transparent picture with much more data then others. Significantly, the salary range is what is most important, and as you can see the top end for CS is $260K, but that is not realistic for most maybe just a few who are the 4.0 MIT students. I will point out that the salary range is quite wide and I imagine is due to the locale, GPA and other factors that we still cannot discern.
