dual channel ram is honestly a great performance enhancement.
in my amd64 system, upgrading my ram made a big improvement. Also, nearly every mobo made recently is manufactured with it because it is an easy and cheap way to grab a bit more performance... and dual channel setups have been around for quite a while now, so this isnt groundbreakin tech (I am a big fan of bleeding edge tho)
I think all of us geeks have probably scared scales away from computers...
