Some basic questions -- SLI vs Crossfire, SSD vs Sata (?)

You don't need multiple monitors to use multiple video cards, since we'd be using the GPUs for rendering on the main screen anyways.

Speaking of links, if you have one where I can read up on it, I'm not up on using two gpu's onto one monitor and getting better results hows that work exactly, I have a ton of extra video cards and if two (not in sli or crossfire) can render different parts of the screen or something that would be nice (do you need to run tiled to do that or can you do it full screen)?

Or does one do one part of the rendering and the other gpu a different part like two gpus one would do physx and the other the other stuffs, if wow supported physx.

Seems you would have to run textures into both video card rams; would that not affect performace. Well I don't know I just use one monitor and one gpu per computer and play in full screen and alt tab between them.

Ya killer nic is usless but I spend 4000 words to say the same thing as to why it is.
