All depends on your interest rate on the student loans... 2%? Drag out the payments as long as possible, that's free money you can even put in a high yield savings account and make more than the interest charged. 7%? Pay it off, because you're not going to find something that's likely going to have a higher return.

IMPORTANT if you do put it toward your student loans, make sure you have it applied to principal; if that's not an option when you pay, speak with someone at the lending company to make sure that happens.
