There is a 3.73 and a 4.10 available, but they aren't cheap. Do you have an A6 or a M6? The M6 comes with a 3.45 from the factory, so I'm thinking 3.73's would not be worth the trouble. The A6 however comes with 3.27's, so 3.73's would be about right.

We have the 3.73s and the 4.10s on hand ready to go. The ring/pinion runs $569.95.
The full install kit runs $254 and just the bearing kit is $55
With the 6spd in either auto or stick form, there really is not a need so much for the 3.90. It was the go to ratio for the 4spd guys, but with them being a thing of the past, 3.73 and 4.10 will probably be the only options for a while.

Looking at final drive ratio of the Auto trans cars, the first gear is 4.03. So that makes final drive stock (auto 3.27) at 13.178. Change that to a 3.73 and you get 15.031. Then lets use the manual trans. First gear is 3.01. So with the 3.45 that makes it 10.384. Then add the 3.73 on there it is 11.22. A good overall change. Not as dramatic, but it works well for either of them. Esp when you factor in effective ratio with tire/rim size as well.
Sorry for the long math lesson, but in reality, any gear change is going to help. Especially for the G8 guys swapping to the Camaro rears that want more boost than stock gears give.

After going 4.10's in my six-speed I will never have anything less. The change is not nearly as dramatic as some may think. It is very noticable under acceleration, but the highway manners are almost better with 4.10's than with the 3.42's, due to the factory gearing being low. I used to barely use 6th gear anywhere but the interstate. Now I run about ~1700 rpm at 60 mph and around ~2100 rpm at 80 mph, which is really about perfect.
I haven't ridden in or driven a 5th gen, but if you're going to spend the money I would not hesitate to buy 4.10's. I think thats what the car really needs to get that 4,000 lbs on 20" wheels moving.
