The i7 series ROCKS! I'd have no hesitation in recommending them for editing.
My only hesitation in buying one now would be that the new 6 core Gulftowns are due out Q1 of next year.
The golden rule of computing applies:
If you want leading edge technology you pay dearly.
The i9 Gulftown is around 40-50% faster than an i7 at the same clock speed, runs cooler and uses much less energy, but costs around $ 1 K. Compare that to the i7-920 after introduction of the i9, overclocked to 3.6-4.0 GHz for around $ 200 or less. Even now you can find them for slightly over $ 200. So have a look at your budget. If money is no object, get an i7 now and exchange it for an i9 when available.
I agree with Jim that the i7 is great. If you consider that his system is more than two times slower than my system on the PPBM score, I can only confirm that the i7 rocks. But also a warning. If the speed advantage of the i9 over an i7 is around 50% for approximately 5 times the price, then I think it is more economical to really fine tune your system, since I have more than twice the performance of Jim, just because of fine tuning.
I've seen some preliminary benchmarks of the new CPU, but have not heard a word on pricing. Where'd you get your info, Harm?
The first benchmarks I saw were last week and these were pulled at Microsoft's request, on a Polish site with an engineering sample. Xbitlabs also had some info but very limited. Various sites make mention of prices around the $ 1 K mark. The Polish site I looked at, Tweakers.net and some others.
Various sites make mention of prices around the $ 1 K mark.
They all seem to be pure speculation, though. I can't find any official word form Intel.
