Stupid question, but why would you ever need two GPUs? Is it just if you have a subpar one to being with? And if you do have two, what kind of accommodations are necessary as far as processor speed, case size, or power supply?

It's to have more performance when you can't play decently at higher resolutions and/or graphic settings. In my opinion, some people tend to go for looks or more power.

Negatives: More heat, power consumption, sli/crossfire support, issues with dual cards vs single cards

The whole reason people get dual graphics cards is because they want better performance for games. but there are some cons as fantastik250 pointed out

There are really only 2 (good)reasons to use crossfire/sli.

1. You bought a card, its two years later and it can't keep up, but you can buy a 2nd one for cheap and have the same/better performance as new cards for less.

2. You have more money than you know what to do with and need multiple high end GPUs to run a highers multimonitor setup.

There also gpgpu compute cases for it but that's different. basically buy the best single GPU you can. Crossfire in a couple years to save money.
