Dual Video Cards

This is only a benefit of dual Monitors correct? And how does it work? Will they just split the screen in 1/2 and only process one side each?

Also, I assume there is no benefit to having it with only 1 monitor correct?
 
No. You'd use two GPU's if you wanted more performance. AMD had Crossfire and nVidia has SLI. They take the two GPU's and make them one.

You can use dual monitors with just one GPU. No need for two.

Depends what you're trying to do. You can use multiple random/various GPUs to support multiple displays in something like a 2d environment, no problem. If you want to use both GPUs to increase performance, then you'll have to buy like-for-like cards and use Crossfire/SLi (which would increase performance on single or multiple displays).
 
they render alternate frames. they don't split it and revert half.

i.e. you get 60fps , each second each one does every other frame, so each one renders 30 frames.

keep in mind your cpu needs to be powerful enough to queue each frame for each video card, and this effectively halves the load for each video card (if one would be at 80% load two would effectively be at 40% leaving extra resources for higher quality or higher fps)

it's obviously a little more complicated than this but you get it
