That's why LGA775 was the last true "great" platform Intel has built.
Everyone will get suckered into changing entire systems from now on...

using i5 2500k since 2010 until now....not planning to upgrade until 2014 or 2015

4.6GHz - 1.1V !!!





5GHz - 1.27V !!!

I was hoping that i can keep my 2500K for at least 2 years. But now , looking at what the IvyB is capable of , feels like thats not gonna happen. Cant wait for the full review and i'll start from there. .

That's a suicide run. Most users even with watercooling should not exceed 1.4V max with IB.

Should wait for ivy bridge or just upgrade to current i5?
So confused and can't make my decision

nice looking? that's almost the ugliest Z77 board ever seen so far.

Still some in stock.

*SIGH* 

it only can be drop down to 1.6GHz and not 1.2GHz.

it still high and not "speed-step" enough.

I'm not surprised if IB had a little problem with temps. Probably people were so surprised that SB clocked well that they would come to expect it to progress to even higher with every generation. It can be due to the process still in its early stage and could improve when Haswell comes out, that is if there are people willing to bet on waiting for another year. Have yet to consider the fact that the die is actually smaller with IB and less surface area for heat to dissipate and the increase in power density of the chip. If you're getting IB, your best bet is to stick to 4.5GHz or less, 4.6GHz possible and near or less than 1.3V should be quite safe provided that you have a beefy cooler like the Noctua NH-D14 or similar.

I don't think there is anything more to be mastered with their Trigate. It has existed with them for nearly 10 years, since 2002. They could have ironed out the issues during that time period and the heat might just be an issue that we would have to accept. As for Haswell, it would definitely be a lot better, according to my sources. It sounds like I'm stating the obvious but Haswell should improve but I'm not quite sure what they could do in a year. I'm already impressed with the fact that Intel is the first fab to actually do a production ready 22nm model while others are still struggling with 28nm.

I regard 4.5GHz to be the most common frequency that people would be able to reach with SB, anything extra is pure luck or you're willing to compromise lifespan for a few hundred extra MHz. As for 4.5GHz IB, it should have better results than a 4.5GHz SB. A 4.6GHz Core i5 3570K should have similar performance as a 4.9GHz Core i5 2500K, so I think a new IB based rig or upgrade to from SB is good provided that you have a SB that doesn't do well above 4.5GHz and you have some decent cooling.
