Atlanta area seems to pay the least, the lowest I've heard is 105k and up to 135k. One place I saw offers 90k but I don't think they'll ever fill it at that salary. I've heard of up to 170k in other states/cities but I can't verify that.

For what it's worth, most students get jobs at the places they rotate during school, people they know, etc. The number of job openings on gaswork is not representative of the opportunities for new graduates.
