The IT job market has been heating up in cities across the country, but not all cities are equal when it comes to the average year-over-year salary growth, according to tech-industry career site Dice's 2012-2013 Salary Survey of 15,049 tech professionals across the nation.

Although Silicon Valley topped the charts as the only market to boast a six-figure average salary, with the median at $101,278, it actually had a 2.8 percent decrease from its 2011 average of $104,195, according to Dice. But, it wasn't the only tech hotspot to see a decline. Hartford, Conn., saw a 3.9 percent drop, from $88,546 in 2011 to $85,130, and New York City dropped 0.4 percent, from $90,042 in 2011 to $89,669 in 2012.

But, it's not all bad news: 2012 marked the first time in the near-decade-long history of conducting the survey in which Dice found double-digit growth in seven markets -- the most ever registered, according to Dice. Continue on to find out which other tech cities enjoyed salary boosts last year.
