Hmm, well the 25% figured I saw was this:

Given the figures you posted I'm not sure what bit tech is talking about here. Also I have yet to figure out how SB is running more bandwidth than Nehalem in the guru3d test considering they're only using 1600MHz memory with the SB rig, which I assume is what their Nehalem rig is also using.

You have a problem with somebody trying to understanding the reasons why it does or does not perform better? You might enjoy just not worrying about it and remaining ignorant of such things, but I generally like to understand those things when looking at a new system.
Intel Core i7 920 Nehalem Quad @ 4.0GHz
EVGA GTX 660 SLI @ 1046MHz
OCZ Platinum CL7 6GB
EVGA Intel X58
