while the 930 on paper seems much better, it doesn't overclock very well at all, in fact the 920 overclocks better, more stable.
and seeing as a 920 is no different than a 960 or whatever the highest end was when the 9xx series debuted aside for the clocking, there's really no point in getting a 930 aside for the 22nd multiplier, which benchmarks show doesn't really matter that much as you can't overclock it as much anyway

Conclusion
While on paper, the i7-930 is a mere 133MHz clock bump up from the i7-920, the fact that it's the same price and is slightly faster means that you'd be foolish to buy an i7-920 now (if you literally just bought one without knowing, then, sorry!).
What really sells us on the idea of the i7-930 though is it's improved overclocking potential. While there's no guarantee that every i7-930 will overclock as well as our test sample, it's very pleasing to see how much better it overclocked than any i7-920 we've played with over the 12 months at identical voltages. Any CPU, let alone one with four physical cores, four logical cores and triple-channel memory, that can run at 4.3GHz with a standard air-cooler is great news. Given that the i7-920 itself is a great overclocker, it's really good to see Intel launching an even more overclockable CPU at the same price, and not forcing enthusiasts into buying uber-expensive Extreme Editions.
The i7-920 was a classic CPU that will almost certainly be included in the next update to the Hall of Fame but 16 months on, it's now past its sell-by date.
The i7-930 is a worthy update and one overclocking enthusiasts should still consider. We'd love a bit of a budget refresh to the X58-ICH10R platform which we appreciate may still push people along the P55-i5-750 or even i7-860 route, but consider it a solid investment because an i7-930 will be fast for a long while yet to come and it will overclock further than an i7-920, making the performance difference between the two CPUs even greater.
