What are the benefits of a dual-core CPU over a quad-core in a desktop PC?

I know that in most cases when you buy a dual-core CPU for the same price you could get a quad-core, you end up getting 2 cores that are faster individually than the 4 cores individually in the quad-core CPU.

I will never say no to more cores/processors. I can always find something for them to be doing. Besides, I can't notice a difference with my Intel Quad Core versus my Intel Dual Core when gaming; perhaps my video cards mask the difference.

The Cache may have a major effect, 4 core CPUs tend to have smaller caches (there's only so much silicon) and having more processes running flushes out the cached data you need for a given process.

It depends alot on what you're doing most of the time I think. If what you do involves using several different programs, for example, web development with TextMate, Photoshop, Transmit, Versions, etc., then it might be advantageous to have a different processor able to handle each. If on the other hand, you're only running one program and need it to be able to run fast, like video editing perhaps, you'd probably less, faster cores. At least until more programs are able to make use of multiple cores.
