Question on Windows Advanced Boot Settings - How many processors ticked?

I feel a bit dumb for asking this but I did a bit of digging on Google and there seems to be conflicting ideas on this so I'm hoping someone cleverer than me can put a definitive slant on it.

I've got an i7 920 running under Windows 7 Home Premium. Going into msconfig and looking in 'Advanced' under boot settings, what should be ticked under 'Number of processors'? I am aware the 920 has 4 physical and 4 virtual cores so should it be set to 8 or left unchecked so the PC can apparently decide what to utilise at boot time? Previously I was running a Q6600 which had the checkbox ticked and number set to 4 but with the 920 I'm not so sure.

Image below as I have it set currently (box unchecked):-

Its a myth that is does what some sites claim it does.

It is there to fault finding, the way you have it above (default) all cores will be used.

I messed with it before and only had 4 Cores, no HT running when I ticked 8 cores for some reason.
