Two monitors with SLI

Is anyone using SLI with two monitors for multiboxing wow?

According to this, their later drivers support the use of SLI with 2 monitors. I was curious if anyone is seeing any performance gain for SLI. They dont specifcally mention using 3d applications in both monitors unless its specifically supported which id say on the safe side doesn't include wow. The only example they use is a 3d game in window mode on the primary monitor and a web browser in the other.

WoW doesn't work one ounce with SLI. It doesn't even recognize it.

Sorry to burst your bubble, but that's completely pointless.

There are some threads in the blizzard forums about multiprocessor support and sli/crossfire. The game engine they use doesn't support it. However game crashes have been reduced quite a bit for users that have their graphics cards bonded (my system is in crossfire with two monitors 1x4 characters). I relooked at enabling crossfire when I tried Win7 and it works fine without a game crash that I can attribute to it.
