I recently upgraded my X3 version to X6. Although essentially similar, there are some great new features and, being now exclusively 64 bit (for Win 7 and 8 only), it's much, much faster. At the same time, it is rock-stable, which was not the case with X3. As a very simple and basic test project, without any fancy work, I dreamt up a slide show https://www.youtube.com/watch?v=nap-Dx8P8wk using some photos I took in Cyprus in 1952. The intro title was done using the new version of ProDad Heroglyph which comes with VP X6 at the start of my learning curve for it. I also checked out how it worked with DV AVI and AVCHD clips (unpublishable!!!) and had no complaints. Recommended!
