In April 2008, Corsair looked at gaming performance between 2GB and 4GB memory configurations. Now with release of Core i7 and triple channel DDR3, they have tested game peformance differences between 3GB and 6GB memory.
Gary Key from Anandtech.com has posted up a blog entry regarding the state of his initial DDR3 triple channel / X58 motherboard overclocking
Bit-tech.net folks posted an Intel Core i7 920 overclocking guide for Asus P6T Deluxe and MSI X58 Eclipse.
Update: Seems Anandtech.com was correct higher vdimm is possible only if you keep a balance between bios voltages particularly the requirement that uncore voltage needing to be within 0.5v of vdimm memory voltages.
