If I understand it correctly, Turbo mode allows you to over-clock your active cores when other cores are idle.
With Speed Step, your cores would normally operate a lower speed, like 50%, and increase on demand. With Turbo, your cores would normally operate at 100% but if one of them isn't needed it gets disabled and the rest get a boost to 110%. (Not sure on the numbers, someone else can correct me.) So my question is what do you consider "full bore"? Do you consider it full bore to lock all your cores at 100%? Or to over-clock all of them to 110%? Or to disable all but one and over-clock that one core to the max? If consistency is the goal, I would keep Turbo turned off. I'm sure the engineers at Intel did some smart math to make sure Turbo would, in general, improve over all performance; but improvements to the average performance might come at the cost of significant temporary performance loss. I don't have any science to back up that supposition, so maybe it's not a valid concern. Better safe than sorry, right?
