My suggestion is to avoid telling a potential new employer what you make now. They'd then work hard to cap you at current + 30% instead of what a comparably-skilled peer might make.
Textminer is right, no need to mention your current wage.
But honestly, it seriously depends on what technologies you have experience with.
But to give you a number, you could very easily get $125k. I bet if you somehow got 100 offers, the vast majority of them would be normally distributed between $110 and $140k.
Mitigating factors:
1. The universe of companies willing to fly-in a candidate and pay for relocation is smaller, so you have less bargaining power. I was able to secure a 20% raise the first time I changed jobs here -- a year after relocating.
2. If you have impressive skills in more lucrative technologies you can certainly make more.
The average salary for a software engineer in ATL is 110-140k?
I talked to 2 companies in Atlanta in 2010ish (MailChimp and a smaller private company) and their salary ranges were well below that ($90-110k iirc). I'm surprised to hear it's so high!
