Seconded.
It certainly does not bother me, however, that will mean the amount of users who are to understand your question is even smaller than it is possibly now...
Anyway, I think what you mean is whether the drivers from the officla DriverPacks or from the 3rd Party DriverPacks are preferred.
I cannot give you an absolutely definate answer (that's for Bâshrat the Sneaky), however, the driver with the newest version (the date given in the INF file) is chosen.
Therefore, even if the driver is already supplied on the Windows CD, if the DriverPacks have newer drivers, they will get installed.
Since the 3rdP DriverPacks are only supplemental to the official DriverPacks, you will not encounter any drivers twice - if a device is covered in an official DP, there's no need for a 3rd party DriverPack for the same device, obviously.
