Reply To: Does ID CS5 utilize the hyperthreading technology of the new i7 intel chip?

Hi, yes it does support multithreading, according to Ann-Marie in her lynda.com tutorial on the new features (which I just finished). You can especially see it at work when exporting large documents to PDF. It hands off the PDF export to another processor while you continue your work. There's a new panel called “Background Tasks” where you can see the progress of export(s).

As a newspaper designer, you should note the column-spanning, column-splitting, and balance columns features. I think those alone are worth the price of the upgrade.

To answer your other question, multithreading support started in Photoshop CS4.
