Hi, the main question is:
Do your computer works fine? If so, you don't need to rush and update.
Do you face any problem that the newer version would correct? Then yes.
Does they improve performance in any game you play? Sure, keep them coming.
Don't rush to update unless you really have to. I'm still on the WHQL 22.5.1 and everything runs just peachy!
Normally this guy reviews the drivers release and He's pretty good at it.
