Actuly im not sure if it was tomshardware or anandtech but i read (something along the lines of) they had to pull OC's down to 4.5 on two of their three test rigs for stability. With the almost unnoticable performance per clock gains, it seems 2600k/2700k will actuly outperform ivy i7's by a decent margin if you are pushing overclocking far (>~4.7ghz?)

4.5Ghz is like the practical limit with Ivybridge with most air coolers, as soon as you pass 4.5Ghz holy shit sticks it gets hot. You get around 5% more out of it (speed-wise) and 20% less power consumption. I think it's also only around 10% hotter.
If you're going for like 5Ghz, you need like a water loop most definately ( for 90% of the Ivybridge anyway), and the Ivybridge is like 45% hotter or something at 5Ghz...
So imo, Ivybridge is a great chip for anyone not aiming to overclock over 4.5Ghz, which to be honest is a lot of us.

I dont really see the point of getting it though. Sure, it has better integrated graphics, but that is irrelevant to PC enthusiast crowd (those overclocking i7's atleast) and you wont actuly gain any performance out of it unless you run it at the same clock as sandy. There is no reason to, as if you are limiting by temperature or ease of overclocking, sandy will give you a higher clock speed and thus equal if not more performance. By 4.7ghz, 2600k will have overtaken the 3770k @4.5, and aparantly also have lower temperatures.

The Ivybridge wasn't built to satisfy the PC enthusiast to be honest, it was more of a platform to deliver and test the 22nm manufactoring process. Ivybridge brings gains to everyone who doesn't want to overclock their chips over 4.5Ghz which my guesstimate will be more than 99% of the market considering prebuilt machines, laptops, people who don't overclock/have chips that can't be overclocked and people that overclock under 4.5Ghz.
One could also argue that a PC enthusiast should have a likewise cooling kit which would let their Ivybridge run at 5Ghz.

No CPU is really designed for the PC enthusiast in mind. Intel would be happier if their chip was better than it actually is for any market segment, but it's not.
Regardless, I'd still take an Ivy Bridge over a Sandy Bridge, even for streaming.
By the way, aren't there reports of Sandy Bridge on 4.7 GHz or more degrading after a couple months of 24/7 load? I'm sure some chips can handle that fine because they can do it on a lower voltage, but not every sample. Well anyway, maybe if we were looking at 4.5 GHz on Sandy vs. 4.3 GHz on Ivy (being more conservative), that's not much different than looking at 4.7 GHz vs. 4.5 GHz.

I dislike having to ask the question of which is better and have a discussion about it though, had hoped for ivy to simply be an obvious (if only slight) step up.

doesn't matter they will all stream fine.
