I think the part I bolded here is the key? As you "have no evidence" you have no reason to think what you're saying is true?
Now, when you're talking about 16fps vs 20fps actual performance during those taxing moments, there is a big difference (even if my 25% guess is accurate), but is that difference worth $700? That's a personal decision.
The minimum fps at any one point in time isn't nearly as relevant to me as how the fps dips below 30- and I can guarantee you it happens a lot more on a X800XL at 16X12 4X8X than a 6800GT SLI at that setting. Unlike you, I'm not guessing:
Doom 3 on FX55 and X800XL 12X10 2X8X:

Doom3 on FX53 6800GT SLI 16X124X8X:

Notice how the X800XL goes much lower for a minimum, even though it's on a faster cpu, at a lower resolution, and a lower AA setting? What do you think would happen if both were tested at 16X12 4X8X?

Ouch. 29fps average at 16X124X8X. If the AVERAGE is below 30fps, how often do you think the framerate is? Half the time most likely? (on a FX55 no less) But what about 6800GT SLI?

Oh. 65fps average on a slower processor.
Let's see- 29fps average vs. 65fps average? I think you'd lose your bet, and your guesses are way off the mark.
I think it's a pretty safe bet to say that the 6800Ultra SLI rig purchased today will be a joke compared to the best single card solution in the $300 price range in 2007-2008 (three years).
So what? Who keeps their cards 2-3years and expects them to be respectable performers? The insane?
