The biggest problem with these numbers and that survey are that the numbers don't really tell you much, and they also tend to skew statistically high, I'd say, since I believe the survey is self-reporting if its the Gamasutra survey. But its really hard to say anything because you don't know whether the respondants were a specialty programmer (graphics or what-have-you), which demand a marked salary increase over the humble "gameplay programmer" most places. The industry also tend to be a place where there's a significant difference in salary between someone who's shipped at least one commercial game and one who hasn't -- probably because of the relatively-high wash-out for first time game devs in high numbers, vs a much-reduced set of people who have shipped a title and come back for more.
I would say, at the very low end, a fresh college graduate at a smaller studio might make a salary as low as around 50k -- a number of years ago I was made an offer similar to that, not long after I was out of school. People who have been around through multiple titles and have a specialty or are very strong generalists can top 100K relatively easily, 120K or more is less common, but not unheard of.
But in general, for the skills and hours demanded, the games industry is almost always less-compensated than other places you could be employed as a programmer.
