Are the Intel "Extreme Edition" CPUs worth the price?

[kylohk]

I was looking up the latest prices of Intel CPUs on the internet and noticed that the Extreme Editions are ridiculously overpriced compared to the regular Core i7s. I've chatted to several salesmen in the PC mall and they said that the i7 is already for high power users, and those Extreme CPUs are nearly 4 times the price of the normal ones. Are they worth it? What type of people are they intended for?

Just asking.

Note: US$1 = HK$7.78
