I'd think anything less than a quad core now will be considered disappointing by most.

Apple is unlikely to care about the marketing benefits of quad core.

I wanted to say that the quad core seems to be a total waste as a personal workstation.

The 3 will be a quad core and something even more forward in progress than a spec bump.

That is how you go beyond 5GHz on a quad core.

I think dual quad core may be a little overkill.

If you want quad core, you can get a workstation.

There is no reason a quad core couldn't do all of that at once.
