Options under Powerstrip and their meanings

[Hard2hit]

I have a question for you guys. Im using powerstrip under Win2k to overclock my G400 Max and I would like to know what the options are on the advanced property page and what the optimal setting for them should be. The options are:

Disable Vsync (which I have selected)
Use 32bit zbuffer (current deselected)
Force Triple Buffering (currently deselected)
Disable write combining (currently deselected)

Could anyone please explain these settings and what is optimal for best gaming performance?
