Some will question my frequent use of ISO 1000 in relatively good light, but I have found that setting to be so good on the 5D MK III that I often have the camera set there if I anticipate rapid action. The bottom line is each photographer should experiment and say what is acceptable to them, but it is important to remember that in many cases the ability to shoot at the high ISO settings improves with each generation of cameras. This is nothing scientific, but I feel safe in saying that ISO 12800 on a 5D MK III is superior to ISO 800 on the old Canon 10D.
