Georgia applications are processed in the Atlanta office.
Atlanta was, historically, probably one of the three slowest offices in the country, with applications taking 9 or 10 months on average... that was as recently as early last year.
More recently, Atlanta has sped up considerably... for example, the two December 2015 applicants on VisaJounrey became citizens in mid-March 2016, faster than almost all the other applicants who filed that month.
That being said, the length of processing depends on your case; you may file at a fast office, but get stuck in background checks (which have nothing to do with your office) for 6 months.
On average, I'd say that most people are finishing in 5-8 months with faster cases finishing in 3 and slower ones taking 9 or more.
If you look through the monthly threads for recent months on the progress forum (link below) you'll see what to expect.. go to the end of each thread and look through the latest updated table. It may be too early to get information from more recent months, but look at February 2016 and go back a few months from there. Look for people who list Atlanta as their field office.

In short, if you're lucky and your case is straight forward, I would expect you to be done within 4-5 months of applying based on how Atlanta has been trending recently. If you get stuck in a long background check, then it'll more likely be 6-12 months.
