>but I don't know if this hardware is supported by CS3?
It is by using the "Render multiple frames simultanously" option (or using Nucleo Pro as an alternative). Please search this forum for more detailed answers on the benefits and downsides and how and why the limitations apply to AE as an 32bit application.
Each instance of AE can only access a maximum of 4 GB of RAM (on Vista64). With the "Render multiple frames simultaneously" option in the preferences, AE CS3 and later can start several hidden copies of itself in the background, which can each address that maxmium amount of RAM, so your machine would ideally use 5 processor cores (5 x 4 = 20 GB and leave 4 GB for the OS.)
In CS4 you can set the number of cores to use, in CS3 you have to do it via a text file, detailed in this post:

PS. On OS X, each instance can address 3.5 GB and on Windows XP and Windows Vista 2 GB (or 3 GB if you are adventurous:
