1. Crossfire doesn't work when games are windowed.
2. Crossfire isn't applicable to all games and is unstable in some games that are supported.
Honestly, unless you are buying the top range graphics card (2 x 5970s) it really is best just to buy the best single gpu and then later you can add another if you need more performance.
First of all, an HD5970 isn't an even a single GPU package, it has two GPU cores on it connected by an internal bridge on the PCB, so you basically invalidate your entire argument by using an HD5970 as an example. Also, these "unsupported" games you speak of are what exactly, Farmville? I highly doubt anything that NEEDS dual-GPU acceleration doesn't already have support for it.
Also, as you can currently see, I have a vanilla HD4870 from the release days of HD4800 back in July of 2008. Even a single HD6850 would give 1.4x of the performance I have now, and adding another one would get me up to ~2.8x on games such as BO that really support it. So I think it makes for me personally at this point. Not so much for you since you already have the fastest GPU in the world.
