I always try 4x first to see if AA works well with the game. Only after that is verified do I use higher AA, but I test those as well since some games just don't like them and end up looking worse and going slower than 4x, or an extremely marginal improvement at best.

I think you can get better overall quality by using 4x and cranking the AS to 16x, and using NVTray to crank up the Image Quality settings throughout.
