No, because you can easily overclock chips a quarter of the price to those speeds, very nearly risk free. The unlocked multiplier of the EEs isn't that useful as both Intel and AMD chips overclock by 600MHz+ completely reliably just on bus speed changes. AMD does offer some cheaper chips with unlocked mults, like the 720 BE or 965 BE.
That said, Intel will be releasing a 6-core EE part next year, probably $1000, which there will be no lower variant of. AMD will have much cheaper hex-cores then too but the raw performance won't be quite as good.
If you're at all looking for value, do not buy an EE. The price/performance sweet spot for a high-end machine is about $200 - the Core i5 750 or Phenom II X4 965.

Core i7s are not going to drop in price until Q1 2011 at the earliest. Their roadmap shows a constant price through Q4 2010. Buy a Core i5 or Phenom II X4 at $180-$200. What do you plan to use the computer for anyway? You may not even need to spend that much; you can get a quad-core from AMD for $99 now.
People that buy them are people who think high numbers and paying 10x over what they should for a product is cool and trendy. No one who cares about price at all should buy an EE at the moment.
