It may take a while for most users to migrate to the new 64-bit version of Photoshop CS4; in the interim, for those 32-bit users, the new CS4 offers a plethora of other significant changes to keep you happy.

CS4 comes with an assortment of new features including a restructured user-interface which in and of itself makes it a worthwhile upgrade for current users.

Undoubtedly the biggest difference in CS4 is that Photoshop is now available in both 32- and 64-bit Windows Vista versions. The 64-bit version allows users who have plenty of RAM to work on extremely large graphics with less hard-disk swapping, thus speeding up operations. This is a significant update given the dwindling amount of RAM currently available to modern PCs.
