Top tips for working with drivers

I’ve tried a couple hardware identifyer utilities (belarc, everest etc.) which are certainly very useful but not always conclusive. I’ve tried a couple of driver manager utilities (Driver Detective and something else (?)) but with very little success with these to date. Can anyone give their top tips for quickly finding the correct drivers online (I’ve used driverguide.com many times which has been useful) or recommend a really consistently good driver utility of any sort. Any additional ‘top tips’ for drivers would be appreciated too.
