Well Im using Adobe After effects and I need more RAM for it to completely render my videos. Right now Im using 32-bit vista which doesnt allow me to use all 4GB of my memory for the application. I have a 32-bit and 64-bit Adobe Master Collection CD. My videos work fine but upon exporting the videos, I will get Errors telling me I have ran out of RAM and the export process will shut down. So I think that upgrading to 64-bit and being able to use all 4 GB of RAM will help the process.
