I too think the gold might look very dated in a year or too - see also copper. I would find other ways to satisfy your gold craving (which I do understand, I seem to have acquired a gold cafetiere, cheese grater and sieve since Christmas).
I would go for chrome, as others said it won't date as much as gold. Can you have a gold focal point other than the sink? You'd be forever having to clean and keep it tidy as it would draw so much attention being gold.
How about using more gold with lighting? One big pendant light or a set of three above an island.
