Proof?
Given IB's are running hotter due to the IHS to die using TIM rather than solder.
Do current SB chips bottleneck current GPUs ?
AFAIK, only very high end GPUs suffer any drop in performance when run on PCIe 2.0.
For most people, the difference in performance between SB & IB will mean that upgrading will come at about the same time. OK, for enthusiasts, upgrading from SB might come a year (or a bit more) earlier, but for the majority, it'll be about the same time.

Seriously man, both chips are awesome but why not go with the new IB? I would.
I didn't, because I got my 2500k for less than £145 just before the launch of IB. I also wanted quiet and reasonably priced cooling. I reckon I saved ~£35 on the CPU and ~£30 - £50 on the cooling. I was also pretty sure what I was getting - a CPU that would be fairly easy to overclock to at least 4.5ghz. I doubt that the lack of PCIe 3 will bother me much during the lifetime of my SB.
Having said that, if IB were a little closer to SB in price today, then I think I would probably go with IB.

This has been in interesting read from what you all have been saying lol. I've just built my very first gaming Rig and i had a lot of help from my friend in what hardware to pick and from my understanding of the CPU's which to be honest isn't very much I liked the features offered by the 3570K it performs really well when I'm playing games. I guess it depends if you really wanna heavy OC if so i believe the 2500K is best for that (i may be wrong lol) but if you wanna just play games and maybe OC to see what it's like (like me) then 3570K

OK i have one of the 1st SB 2500k. (I have OC to 4.8 on Asrock Falal1y P67.rev B3. Didn't go higher. Pointless. Only 4.4 on Asus P67 Deluxe.Max.1st rev.) My Son has the Asus now with Intel Celeron G530 2.40GHz. I have a Asrock Extreme 6 Z77. I was thinking of giving him my SB and getting a 3570K or 3770K.
Main uses would be Gaming.
I also have a canon 7D and while be starting to use video.
GPU is 7950 880mhz.
Win 7 is on a 256gb Sam 830 and I have 9 hdds in my box plus 2 external drives .
Would I NOTICE any benefits from the IB chips. Apart from encoding?
Can some one provide a link convincing me to upgrade?
Cheers guys.

Unless you are running multiple high end GPUs and can take advantage of PCI express 3.0, you will notice zero difference by upgrading to a z77 and a 3570. It is pointless for the vast majority of users including gamers.
As the guy above me said for gaming and general use you won't see much difference, but for video ivy bridge encodes ~1.5x as fast as sandy does when using quicksync.
The question isn't whether IB is faster than SB at the same clock speed - obviously it is, but only by 5% to 10% I understand - but whether the SB can be overclocked more than 10% faster than IB. I thought it could, based on the poor thermal conductivity of the IB packaging which limits them unless you use lower-than-ambient cooling (which gets silly in cost and trouble).
But does anyone have figures for what is typically and RELIABLY possible, using a good air cooler? Other things being equal, a SB chip at 4.5 GHz would beat an IB chip at 4 GHz, but if they can both do 4.6 or so it's a different matter. Or if new SB chips won't overclock very far, (why not? What have Intel changed?)

For crap Cooling IVY
For good Cooling Sandy
I had both on my water cooling. I was not hapy with clocks of IVY what so ever 4.5 was max i could get out of it with 93c max in ibt. On sandy 5ghz i get 86c in ibt. Same cooling same liquid ultra thermal compound same day.
Who cares about few Wats anyway when your blowing 160f for cpu ?? Better off getting energy saving bulbs all around the house or **** like that.
If you dont need anything more than 4.3-4.4 i would go for ivy with 20f cooler.

Debatable. The benchmarks I've seen suggest Ivy is 5-10% faster than Sandy, at the same clock rate. So 4.7 GHz SB should be as fast or faster than 4.3GHz IB.
Lord_ZED was claiming 5 GHz for SB, though at too high a temperature for my liking.
Agreed, the Ivy has no problems with heat up until the 4.5 Ghz mark at which point I think you cant get a Sandy past 5.0 Ghz easily? So buying the Sandy because it can overclock better is like buying a BD over i3
got a bad chip then, my ivy 3570k @ 4.5 idles at 18-30c, games max it to 60c and 24 hours on prime got it to 82c all on a phanteks ph-tc14pe

I have the same question as the OP, but I want it to run quietly (pref stock HSF) and will be doing some video editing and conversion so an overclock would help. No gaming. Which one for me?
Price is fairly important too as I'll need a new motherboard and RAM as well.

dww
I dont care about frying my Sandy ----> Got intel protection plan for it. And on 8h prime it maxed out at 78c. IBT is what gets heat out of those CPUs :] Good to melt in fresh thermal compound. After 8 hour session of gaming it maxes out at 65c or something so good 2 go
Ivy chip i had for a week was not able to get 10 passes of IBT normal @4.6 no matter what i tried . It was not one of good ones cos for stable 4.5 it was sucking 1.36v core and u all know what that does to core temperatures on ivy :/
