I'm new to this and I can say, it does make a difference. After a few renders in P5 I really noticed it. Yup, me, too. I had to reinstall my OS a while back and have been reinstalling applications on an "as needed" basis. I didn't install the memory management program right away, mostly because I couldn't find the CD it was on, and then when I found the CD and installed it, I was kicking myself for waiting so long to put it back on. I really can see a difference, particularly, as you say, after a few renders. bonni
