I am no pro at this but i have read that series 10.xx and upwards are optimized for geforce 3. they all support various "extras". like dual monitor screens, 3d spectacles etc.
one major reason why i used my 12.00 drivers is because it has got 4x FSAA setting for ogl.
the 6 & 7 series of drivers are supposedly optimized for the geforce. they perform the best when it comes to mad onion bench marks with geforce 2 chipsets. (although the gain or loss is really minimal and unnoticable to the unprofessional eye)
so what you ultimately choose is very subjective. for me, the 4x FSAA rocks

and 12.00 got rid of the flickering problem i had with 11.01. that is why i ended up using it.
nothing like taking a chance and finding out if the driver is right for you or not. you can always uninstall them if they cause conflicts for you.
i have heard that certain mobo can cause conflicts with geforce cards using certain drivers, unfortunately, i am unknowledgable enough to be able to tell if your mobo is going to be one of them. maybe somebodyelse can help.
