Well wouldnt that be the video card making it run smoothly? I am in no way arguing that 1GB isnt better than 512MB I just want to know how and why.
I work in the 3D animation industry and the more ram you have the better. Example: I need to render an indoor scene of a... erm... restaurant (just off the top of my head). The geometry in my scene takes up around 2 MB of storage space. The textures take up about 400 MB (hi-res+bump+specular+diffuse+masks+etc.). Since I have a fire place in my restaurant (rural German type) I need additional MBs for my fire made out of particle systems or Fluid Effects (Maya), say another 50-80 MB. I should stop here or I will bore you. Now I press the "render that stuff" button and all of that crap is dumped into... you guessed it - RAM. Now a quick calculation will give you: 2+400+80+200 (the last is for various mysterious stuff that happens during rendering) = 682 MB. Now imagine that I have only 256 MB RAM. Half of it is taken by the OS, another 30-40 MB by the 3D program itself, some more RAM is eaten up by pointless little progs like ICQ and stuff. So now I have less than 100 MB free. That means only a fraction of the scene will be loaded into memory and the rest will have to be swapped from the harddrive on-the-fly. I don't know about your HD, but mine is a few thousand times slower than RAM. Therefore the rendering times increase dramatically, I lose time and money, nerves, weight, my wife, sanity, etc. On the other hand if I had 1 Gb of RAM all of the crap gets dumped into memory and the HD is left alone for the duration of the rendering process. I do my work faster, I get paid more, me and my wife live happily ever after gaining weight, reading smart books and not once calling the family psychiatrist. Same sittuation with video editing. A 5 minute clip of uncompressed PAL resolution (768x576) video (without sound) may take upwards of 1.5-2 GIGABYTES of storage space (if it had been edited). So there you have the reason for large amounts of RAM for graphics and video editing. Hope this helped and I made SOME sense...
Enjoy.
