While the game seems to run fine, whenever I try to open it, I get this:

This message makes me nervous. At the link, AMD's auto-detect seems to be broken because it never has an update for me. I manually found my drivers (here) and installed it. Thing is, the installer didn't even say my version was that old. My version was something like 9.0.0.02.0.0 and it updated to something like 9.0.0.12.0.0. I'll try restarting my PC, and if I get back on, I'll tell you guys if it worked.
Since this is the only game triggering it, and past reports mainly pertain to L4D which seems to work fine, I'm nervous. It only effects BioShock Infinite.Restarting fixed it, although I'm still not sure where it got the version number it was getting.
So I got Industrial Revolution pack, Collectors Edition pack, Early Bird pack, and China Broom. Turns out you need to get your gun code when retrieving the game, so no Best Buy sniper. But I suck at snipping anyway. <3
Edit: I just entered that place with the tiny pig statue in front of it right near the start of the game. Took lots of screenshots. I could apparently somewhat handle ultra, but I didn't want to risk it - everything was too beautiful not to kill my computer.
