Intel Core i7 940 Nehalem 2.93GHz VS 2.66ghZ

Hello, I've been searching to find any information that puts the Intel Core i7 940 Nehalem 2.93GHz vs the 2.66 version.
Its over 250 dollar difference but is it worth it? I do plan on overclocking.
Let me know, I do highend 3d graphics and computer design, but 250 bucks these days is a good chunk of change. Thanks for any info or reference links.

Check Tomshardware forums and hardocp.

From what I've seen, no it's not worth it. Just get a good CPU cooler and OC the 920 to 3.4GHz

Get the 920. Can easily overclock to 4Ghz

Nice! Thanks guys. I'll save some money and go with the 920.
My original plan was to go with an AMD Phenom II 3.2 but for 40 bucks more a friend talked me into looking at going back to Intel and looking at the i7 chip. I'll definitely look at the other motherboard, the only thing that could be as interesting was the full 16 bit SLI with 3 cards. I thought for upgrading over the year, that would be pretty impressive. I'm still looking of course.
