Although this site isn't about job searches, the fact of the matter is that most network and system administrators have an interest in getting paid for their efforts. (Personally, I didn't get into Cisco networking for the glamorous parties with Paris Hilton, but maybe you did?)
There's absolutely nothing wrong with having a salary in mind when you go into a job interview. Obviously, it doesn't guarantee anything, but knowing a ballpark value might help answer the nightmare question: "What salary are you looking for?" (Interview hint: "As much as possible" is apparently not the answer they are looking for.)
And to answer the really important question... How much should a Network Architect be paid in Texas?
So, how much should you be paid?
