"Even quicker" isn't a phrase frequently seen in the same paragraph as "Poser 5"... but I'd guess the answer to be "yes" with the REAL answer being "No". I'll clarify that in two parts... 1. If your notebook is using the swapfile/paging to disc/using virtual RAM (which you'll notice as hard disc activity whilst using Poser, and whilst rendering) then more RAM would likely decrease this by providing much-needed real memory, which is much faster than your hard drive. If what you do now, for example, would comfortably fit in 384MB then the PC wil ldo it grudgingly with 256MB of real RAM, but will eaily do it more quickly with 512MB of RAM installed. 2. If you add memory to your notebook and Poser 5 gets quicker, you will add to the complexity of your designs until such time as speed returns to "merely tolerable" instead of "pleasantly fast" - because you can! The way of Pseronal Computers since the early to mid 1980's :)
