Here is my humble contribution with my new E8600. Needs a little more voltage than I would like but that's the luck o the draw me thinks.
E8600 Q820A604
8.5 x 480 4080 MHz 1.248 vcore under load
Mem ddr3 1600 7-6-6-24 1T trd 8.5
Here are some 3d benchies of 9 x 480 1.328v under load with 2 Diamond XOC 4870 800/1100 in CF
Still trying to get 9 x 480 completely stable. Not sure if it is cpu or
nb voltage which needs to be increased. Running these two 4870's really stresses the
nb.
