FYI, some of the same improvements are available with Carrara (DAZ).  Poser and DAZ content imports pretty well, including scenes although, after a bit of a learning curve, you will probably just set up in Carrara.  C Pro 7.1 is much less than Vue infinite 7.5 (especially the platinum price, or if you wait for one of the regular DAZ sales) and has great lights and excellent rendering speed and quality.  I would take a look at both.

One note - Carrara is still a 32 bit program, but I run 32 bit XP, so it's not an issue for me.  It is apparently well multi-threaded since I use an intel Quad core and all four cores max out when rendering (fast).
