With the Alabama-LSU game at 8PM, it's doubtful that there will be much demand for the Clemson-Duke game in Atlanta. The Atlanta Clemson Club usually watches it downtown (Deadwood Saloon, I think) so that might be your best option if you stay in town.
From Sugar Hill, it's 45 minutes downtown or about 90 minutes to Clemson with cheaper beer and friendlier folks. No brainer - I'll choose the Esso everytime!
Taco Mac will have all the games on a screen. The audio will be LSU/AL more than likely, but sometimes that is a good thing. The announcers two weeks ago were terrible.
