Is Lacerte primarily a single core application like Quickbooks?

Looking to replace hardware and, and just learned that for the most part, Quickbooks is a single core application, and need to know if Lacerte is the same way.  If they are single core, I would be looking for processors with the highest speeds vs cores.  Installation only states a requirement of a dual core 2.4ghz, which I would not consider for running anything other than web browsing.
