What's wrong with the noise levels? Note that their graphs are a little misleading as they don't start at zero...so the differences in their graphs look huge, when in fact the differences are small.
"Noise levels are only slightly up for the dual card setup, and still better than the smaller 8800GT which pumps out 70+dB when under load."
Slightly up for the dual-card setup, and it looks like they're using 3850's with the dual-slot coolers which are probably louder than the 3850's that use single slot coolers, so if you used two of those, it'd probably end up quieter.
