Svdl's post sort of answers the question, really. If there is no render speed boost or ability to create and render really complex scenes with lots of characters, props, lighing effects, atmospherics, shaders, etc, etc, it doesn't seem that, for now, x64 would be worth the effort. Thanks to all of you for your thoughts on this. I love P6 until it comes to render time. Then, grrrrrrrrrrr! I also found another good thread about alternative render engines that also addressed the source of my frustration. Scamp
