Developer Drivers Vs Microsoft Built In Drivers?

Whats the recommended installation procedure for installing drivers for specific hardware from a developers site or using the windows 7 default drivers?

For example when I install my windows 7 x64 Betas it found and installed the drivers for my chipset and everything fine. However browsing my Motherboard manufactures website I see they Drivers for chipset, audio, and other components I can download.

Would you recommend I stick with Microsoft drivers or use the drivers on the developers site?

If there's no seven drivers from mfg, stick with MS's.

If there is seven drivers from mfg, stick with mfg's.

If there's no seven drivers from either MS or MFG throw vista/xp drivers.

That's what I'm doing so far.

What I thought however was concerned as some of these are like 1 month or 2 months old labeled BETA and I was thinking maybe the newest drivers are in the RTM or final builds we have been playing with.

As you say some manufactures are quicker than others for upgrading drivers. I tend to stick with MS drivers inbuilt unless the manufactures drivers give extra functionality or maybe greater performance like in the case of sound and graphics drivers.
