In order to get 4-card SLI/X-fire, previous chipsets had to use a middle-man, which greatly increased latency (look at the P67 UD5 vs. the P67 UD7 in 2-card X-fire). Amd will be running 4-card SLI/X-fire meaning there will be two slots at x8 performance. The old method presented a pretty large bottleneck because it was two gpu's trying to pump math through an 8x connector. Now, on Amd, it will still be the 8x connector, but one gpu per connector. This is a pretty big deal, IMO.
You need two NF200 for 4-Way SLI. Maybe it's going to be different for 990FX, don't know. But so far you do need them.
