I have Vue Infinite 5 right now. I haven't used it as much as I expected to, mainly because of Poser import memory problems with my wimpy old machine. Now I have a more powerful system with XP64, quad core, 4 GB RAM, but V5 still chokes on complex scenes.

Is it worth the $299 to upgrade to V6? I heard that it's memory handling has improved. Should I wait for a sale, or does the price stay pretty consistent? I would love to be able to do more complex scenes in Vue. Any advice much appreciated...
TIA
