For every one out there thats not capable of a decent OC then yea it will be worth it.
Strange comparison, like Core i7 wont OC or people getting the i7 have no idea about overclocking.
That's why all the preview benchmarks compare the Core i7 and Core 2 Quad at same clock.
If you like to compare otherwise here is what AnanTech
said in one of the early preview
At 2.66GHz, Nehalem is already faster than the fastest 3.2GHz Penryns on the market today. This thing is fast and this is on a very early platform, keep in mind that Nehalem doesn't launch until Q4 of this year.
Plus Core i7 version of Nehalem is not all about clock speed. It's about.
Integrated Memory Controller (IMC)
Triple-channel DDR3 memory
Hyper-Threading (4cores 8 threads)
4.2 version of Intel's SSE
Turbo Mode and much more.
I'm not going to describe all the above but if you don't know yet here are some articles to read or Google for many more.
