If I'm not wrong, a single postgresql sql query cannot be spread over two processors, but can it be spread over multiple cores? If that's
No - a *core* is another cpu, basically you will have 2 or 4 cpu's in the one physical package.
HT creates 2 virtual cpu's sharing the same cpu resources but the cores are seperate cpu's in themselves.
The Quad-core will only benefit you more if you have more users running queries at the same time. Each core can run a query at the same time without slowing the others down (allowing for disk access/FSB limits).
