video drivers

My question to the grouop when updating drivers from Nvidia do I need to un-install older version drivers before installing a newer version. For example I am using the XP driver build 21.81 for the gforce3 card. I see that a newer build is now available build 21.83 do I have to uninsatll 1st or do video drivers insatll on top of older builds. Thx in advance

I’ve got a Compaq q/ a built-in Nvidia TNT (which sux), and i’ve just installed on top of the current drivers and everything worked fine.
