Quote - Rule 0 of system admistration (both hardware and software):

If it ain't broke, don't fix it

My corollary: When you change, usually you change for worse.

Interesting strategy, i for myself usually prefer the exact opposite:

 Upgrade drivers when everything works fine.

By doing so, if the driver is bad, i know that the driver is bad and can install the old one again. But if i would wait with the upgrade until i get a new graphics card (which will happen inevitably anyway), i would need to install the card and driver the same time, and if something does not work i would not know if it is the driver or the card or both, usually resulting in hours of plugging/unplugging and installing/deinstalling.

It depends on personal preferences, in the end you weight some small hassles (upgrading now and then) against one big hassle (defer all upgrades till you must).
