Update Video Driver

Windows Update shows an update for my Video Driver (Nvidia geforce2 mx w/tv out) on a Dimension 4400 desktop running XP Home. I've heard it's better to get the driver from the manufacturer. But doesn't Dell modify these cards before shipping? From what I see I could do the driver update from the Device manager or from Windows Update or from Nvidia or even from the Dell Website.

So, which way should I go? If my video card seems to be working fine with a driver dated 2001 should I even worry about it? Thanks.
