yes the only difference between the new NF7S2 and the NF7S2G is Gigabit ethernet.

That VCore regulation circuit will only be designed to cope with about 1.9v (1.65v + 14%)... on the other hand, the Gigabyte 7N400Pro2 uses "stock + 10%" and i know of guys running 2v 2800MHz 24/7 stable with water... we'll hav to wait and see I guess
