I would find it hard to believe that Adobe on anything since version 2 or 3 isn't multithreaded to some extent. What I expect to see in CS3 is more breaking down of processing into threads instead of just UI and processing as separate threads. The question of dual core vs quad core is not whether your threads are running on all 4 processors -- with Vista I would expect that -- but rather how much is your CPU utilization. If a dual core has 50% spare capacity and a quad 75% I don't know that you're getting that much advantage. Certainly having more RAM available is some help but really the disk i/o subsystem is the bottleneck. Using SATA-II with a hardware RAID controller a dual core should render video much faster than a quad core trying to pull from a firewire I drive and work with a single SATA-I drive to store the rendered video. This is assuming 2+ GB RAM so that there's enough room for the buffers required for the application and the disk and the OS and all the application code.
Increasing CPU processing power available puts even more emphasis on the disk storage subsystem. You'll get the very best disk performance for rendering video in a RAID 0+1 configuration, not RAID-5 (or 6 or 7). HW RAID-5/6/7 is certainly superior to single drive but the stripe-mirror configuration will surpass it. You'll need 4 drives to pull it off and you will of course only have half that available due to mirroring (i.e. 4x500GB drives = 1 TB usable space, not 2). > I now use a Quad (QX6700) and Vista with the CS3 Production Premium and > notice everything seems faster than with the previous almost-3GHz single > processor and XP.
