Nice; This is the only book of which i have all three editions.

You might also want to get the 1st edition to understand how the earlier 32-bit programming differs from the current 64-bit programming. You can probably get it for free/throwaway-price.

Pair your CSAPP book with Advanced C and C++ Compiling by Milan Stevanovic and you can become a "Low-level System Programming Guru" ;-)
