Re: what is the diff. between SLI, and normal?
The only downside is that you have to get the high-end cards. The good news is, unlike SLI, CrossFire can link 2 different cards together. SLI has to have 2x 6600 GT's or 2x 6800 GT's etc, while CrossFire can have different combinations like the X850 XT PE CrossFire Edition and a normal X800 XT or a X800 Pro and a X800 XT etc.
