> 1.) Is OpenGL rendering faster (With a GTX 460) or is Render Multiple Frames Simultaneously faster (Athlon II x3 445)? I read on one of the FAQ that you can only use one or the other.
They accelerate entirely different things. Don't use OpenGL for rendering for final export. I leave my preview mode set to OpenGL - Interactive, and that's it.
> 2.) After Effects will stop rendering with at least 10-20% RAM still left over and even call it complete. Why is this? I have tried every setting in the book and I can't get it to use any more RAM. Also in the Render Multiple Frames Simultaneously section I can't get the RAM avalaible for AE over 2.5GB.
You have 4GB of RAM? Your OS and other software need RAM, too. After Effects using 2.5GB out of 4GB is about right.
> 3.) What is the difference between the space bar and the 0 key? As they both seem to do the same thing, and niether get very far into the movie before stopping.
Read the documentation:
The 0 key on the numeric keypad starts a RAM preview.
I am still a little confused on my first question (It could be my noobishness ). What do you mean they accelerate different things?

Please begin at the beginning and read the basic documentation first. Here's a good place to start:
Thank you . The compared links were very helpful.
