I think the old adage that games are not optimised for multicore is less relevant these days - some games already are optimised for multicore, some games have been optimised for dual core already for years. Any CPU you buy now will last anything from 6 months to 3 years or more, and the trend is certainly for games to support more cores during that time.
The quad cores don't overclock as well, or perhaps more accurately, they don't clock as easily on *all* equipment - some chipsets or boards get less impressive boosts than others. The dual cores are definitely overclocking kings.
A quad is definitely the best choice if you're doing a lot of intensive computation. A dual core will give you better bang for your buck gaming right now, but will see diminishing returns with time. For overclocking e-peen, dual core seems still the best way to go.
