Yes, make sure you remove SLI. It doesn't offer any compelling benefits (and in fact probably slows things down, among other problems) for WoW.

I dare say it because Vista isn't good for much else but you MIGHT want to try switching to Vista and seeing if that helps out at all. It handles multiple monitors and DirectX much better than XP does and should, in theory, offer far better framerates.

There is no reason

1 Video Card 1 Monitor
4xWoW Stacked
Frames: 90-100fps
CPU Usage: 65-70%

should turn into this when you DOUBLE the amount of video card power.

2 Video Cards 4 Monitors
1 WoW Per Monitor
Frames: 15-25fps
CPU Usage: 35-45%

I mean, I assume you are bumping up the resolution and all but still.... this speaks more of a driver issue than anything else.
Well regardless of what he has in the video part of WoW, wouldn't keyclone maximizer resize everything? And power supply like someone said earlier could factor in.
