Does crossfire exactly work like SLI?

Exacly? No. It uses different drivers (of course) and I belive you need a dongle for ATi cards (As nVidia ones have a bridge connecting the two cards inside the PC, correct?)

I also know the cards do certain crossfire features differently... for example the Crossfire cards do Ant-Aliasing differently. I don't konw of any other differences other than that...

The concept is the same. SLI uses a "SLI Bridge", while Crossfire uses external cables to connect the two cards. Most Crossfire setups require a Master card. SLI needs two same GPUs.
