I don't think that's right. 3870 uses 105W, which is massively less than R600 or G80 (less than half), and less than an 8800 GT by a small amount.
at idle, the 3870's are underclocked to 300MHZ, and use much less power than 8800 GT's.
I would think that a card with two RV670's would have a TDP of ~210W or maybe slightly more.
I'm pretty sure G80 uses about 230-250W or so under load, and R600 uses about 280W
