I doubt it, Nvidia are not exactly in a hurry to pump out new cards. They are playing us for fools at the moment and renaming current technology to sell us.
I would go for the GX2 also, if it means RMA'ing a board just to go SLI i wouldn't bother.
If you can't afford the GX2 why not get the HD3870 X2? It is a great GPU, performs just a slight bit under the GX2 and is a hell of a lot cheaper.
But as they stated, a 550W most probably will not cut it. The GX2 and the X2 both use a fair bit of power. You most probably looking for at least the Corsair 620W before you consider a dual card or SLI.
Even if some people say it will be sufficient, i wouldn't risk hardware of that price just because of someones word.
