I did things like turning off Aero, indexing and other things just to free the computer up for more important tasks, but not necessary (although Aero is a memory hog). As for running Poser 7, it does run much, much better for me if when I render, I render as a separate process. Poser 6 will bog down for me if I try to cancel a render in progress at which point I normally need to just close the program. Other than that, it runs fine.
