If you're not sure whether or not you can run the game to your liking, we've learned the following:
Generally speaking, the 560 Ti can run the game on 'High' settings; the 570 can max the game out; the 6870 can run the game on 'medium-high' settings, the 6850 should run it around medium-high as well, and the 550 Ti will run it on medium with some gizmos disabled. This will vary based on your other system specs, but as a general rule of thumb, it should help you figure out if you'd be happy with the settings.
I should note that the game looks fantastic no matter what, so don't let the graphics settings discourage you. Remember that this is all about relative depravity -- BF3 has high specs because it looks good naturally, so it has higher standards.
Enjoy the rest of your shopping weekend!
