I am familiar with Georgia Tech, and have a few friends there. My GPA is not so great after randomly leaving town last semester, but I can always bring it up elsewhere.
I was just browsing that same page, actually. GT is a good school.
GT also has several public events where there are profs / researchers showing their projects which you can attend (especially if you are a student) and possibly even work with them (if you can help with something specific). You should definitely come visit and get to know them. When you apply to get in, having a rapport with a professor goes a very long way to getting in.
