You should not saw the boards at all.
Use a utility knife or one of those razor blade knives where you can break off the blade bit by bit to get a sharp edge. Cut through the paper and a few mm into the gypsum on one side where you want to cut, preferably support against a piece of wood or similar to make it straight. Then simply snap the board along the line, finally cut off the other side's paper layer with the knife.
But sometimes you do need to saw, for example, pipe penetrations, feel free to use a scrappy jigsaw or possibly a circular saw because the gypsum dust wears terribly on the bearings in the machine, so ruin a cheap machine. Or borrow your neighbor's nice expensive Festool TS55 ...
(just kidding, but you understood that..)
In outside corners, spackle in one of those steel rails, so you avoid having corners that get damaged so easily. The corners also become much easier to make straight.
Gypsum should above windows and doors and under windows be joined "in the middle" of the window/door, i.e., not directly above the frame.
edit: I seem to remember you could download a reasonably good material on Gyproc's homepage, but now it doesn't work for me. I don't know if I have too high security settings, for example, against pop-up windows ...
But you can try yourself.

Use plasterboard screws, not chipboard screws. Screw with cc20-25 (I believe that will work well).
Norgips Assembly Manual p 1-20 (2004) (1,240 Mb) seems to cover everything...
Very good.
Very good.
I remember that too, but you apparently have to register as a "Gyproc Partner" to access those files now. However, some of that information also seems to be available in their "Handbook for the Home" which you can download without registering.Mikael_L said:

Preferably offset. Don't forget to leave a 3mm gap between the OSB boards. Also in corners.Honeybun said:
