No overclocking for mainstream Nehalem?

[GoThr3k]

depends on the sports or on the hobby -> car tuning, without $$$ nothing happens there.

now, thats a good example, i always compare overclocking to car tuning, you also have different categories (Drag with different classes, circuit, etc.) altough you will get the best results if you have the most money, you can easily beat a similar car then yours in a different class(lets say, max 250hp) if your skills or luck are better then your opponents.
