First of all, the golden age of the Dutch was ended because of the dutch being attacked in 1672 by France, England (this was the third anglo-dutch war) Munster and Keulen (in Dutch, don't know the english name exactly.) the Netherlands was protected by the Holy Roman Empire, Brandenburg, Spain and the Dutch themselves (like duh)
The war was ended about 6 years later, however this ment the end of the dutch golden age, after which the dutch economy went down and the Republic was going down completly, although it would take untill 1795 that the republic was done for.
Now an early victory would mean that 1672 (that all-out war) wouldn't have happened, probably at a certain point the Golden Age would've stopped, however it would probably have lasted for anohter couple of decades. An all out victory for the dutch.
Well the Dutch would have had more difficulty with being a big empire, they need to protect their borders in continental Europe (although there's a chance a longer Golden Age and a victory over the english gives them more confidence.)
Also the dutch holdings in North America (including New York/New Amsterdam) would've remained in dutch hands, what would've happened with that?
