Few questions about GPU clocks and overclocking

So, I'm hoping to get an MSI 1060 Gaming X soon and I have a few questions about OCing and Afterburner.

1) Generally, on any card, if you increase clock speed by X% does it mean your framerate increases by X%, i.e. do they scale proportionally?

2) As soon as you quit Afterburner, does the clock speed instantly return to stock?

3) Since I don't want the MSI Gaming App, I can't change to OC mode but rather have to change the speed manually in the Afterburner. Will I be able to reach the clocks the app applies in OC mode without fiddling with voltage? In other words, is overvoltage applied when you choose OC mode or is all on the stock voltage level?

And the most important question:
3) What about the "apply OC at startup" check box? Does that mean that Afterburner applies the OC at startup or is the new clock speed set anywhere on the card physically? If you removed the card and put it in another PC, it wouldn't remember any of those OCs, right? Are they all just written in your system (in the Afterburner specifically), and not in the card?

Thanks, any help will be appreciated! :)

I don't think it necessarily has to start AB to apply overclocks on reboot. Could be there's some registry value or whatnot that AB can write to, that the drivers will read from on boot.

I haven't used AB for a little while (using AMD's Wattman tool currently), but from what I remember if you applied an overclock and then exited the program, the overclock would still be in effect, at least until reboot. If I had to guess, I'd say when you apply the overclock it gets set in some sort of temporary way in the driver, which then uses that value when controlling the card.

So, basically "apply OC at startup" is just starting Afterburner and automatically applying OC you'd have to apply later manually?
And how do you mean OC stays after Afterburner is closed? If you exit Afterburner (not minimize), the card returns to its BIOS clock speed, doesn't it? What will be saying to the card at what clock speed to run if you close the application?
Or do you just mean AB remembers the numbers until you open it next time?
