Answers.Body: <p>As non-linear video editing is random access by definition (that's where non-linear comes from), you will benefit from more RAM at least until you can fit all of your source footage in memory. The more data you can leave cached in memory, the faster access you can have to the footage whenever you need it.  (I'm not sure exactly how Premiere handles this, but that is the only thing that would possibly benefit from insane amounts of RAM.  If it isn't able to cache it all, then you would only benefit for however much it would bother to cache.)  On the After Effects side of things, more RAM does mean more space for RAM previews.</p>
  
  <p>Processing speed is really a very secondary concern when it comes to memory as things are a predictable and linear process at that point since the computer can anticipate what is coming and data access is not going to be the limiting factor at that point, but rather processor speed.  DMA can retrieve data from the hard drive in to RAM as processing occurs and the processing of individual frames and groups of pictures isn't going to require that much memory space.  </p>
  
  <p>Some high memory consumption processing might benefit, but the primary use of RAM is going to be for holding assets in RAM for quick access while working with the footage.</p>

Body: <p>From my experience with programming I know that just throwing more memory against even a well paralized program will not speed it up after a certain limit due to various practical limitations (tasks can only be split in so many parts, waiting==processing or countless of other scenarios). Is there a limit at which which Adobe Premiere Pro doesn't speed up significantly anymore? Does it make sense to build a PC with 128GB or 512GB of memory? (My colleague is considering building a PC with 128GB and I am just a bit skeptical of this being... worth it, though I might be absolutely wrong as this really is not my area of expertise (and just for the record, I know that it's a 64-bit application and that it can address all available memory up to windows' limit, what I am asking is about the practical world)).</p>
