Quote - All he means is that Poser 7 will not make use of the 64bits, only Poser Pro does when rendering. Poser 7 will not benefit from the CPU, it's 32bits still, but it will benefit a lot when upgrading memory, especially when running WinXP64. If you run WinXP Home then 4Gb is a waste, it cannot handle more then 2GB.

4GB is not a waste. XP Home can handle 2GB per process. With only 2GB, you will lose about 1/2 GB to all the resident junk that accumulates in Windows (your printer etc.) With 4GB, you can still be running your browser, even photoshop while a render is going on. (You will have worse speed performance, but not memory problems.)
