im actually looking forward to that, i stream movies to my LCD TV in our living room through the HDMI on my board, it does pretty good, but suspected 30%+ improvment on the IGP would be awsome.

Mine refuses to go past 4.8Ghz on custom watercooling, so no.

The reviewers 2600ks hit 5Ghz, I'm waiting to see, y'know, the average OC and not what some people may possibly get.

If you don't have an SB setup and the price is only about $30 more than the 2600k then it makes sense. But to sell a 2600k and buy this is silly.

IB is a "tick" in Intel's "tick tock" cycle.

yes some rare 2500ks and 2600ks can hit 5ghz on air, but only few and far between can keep the vcore below 1.4 while doing so.

IB is comprised of cherry picked SB cores, so its far more likely to kit 5ghz on air than a standard 2500k or 2600k bought at a retailer.

and correct me if im wrong but dosnt the dye shrink help improve cooling?

My apologies, I seem to be completely ignorant on the subject. I think the fact that Westmere did not have a mainstream compotent threw my whole Intel Roadmap off.

So is it safe to conclude that it's best to upgrade only when there is a "tock" because this will net the greatest performance upgrade?

Would that also mean that a "tick" is merely a side-grade with better temps?

Depends on the case. A tick can be a lot better depending on the factors, like in this case, 3D transistors. 32nm to 22nm wouldn't just decrease temperatures, it would vastly decrease power consumption and increase overclockability. Count in the 3D transistors, and you have a massive difference in those compared to SB.

2700k is cherry picked 2600k in factory. So 90% of 2700k will do 5GHz easily.

may i ask, jus for my knowledge, do all 2500k's have the same maximum multiplier?

also for the thread, imo 2700k are just for people who want to OC the crap out their cpu, for mainstream users, there will be very little support to buy the 2700k over the 2600k if the price difference is above $25~, with $20-30, u can buy something like the hyper 212+ evo which is more beneficial than 100-200mhz increase

Most do now.

But this is like going from the i7 920 to the i7 930 really. The longer they make these chips the higher quality they will become, and thus the higher they can safely set the stock clocks.

No, the max multi is really a ceiling in overclocking Sandy Bridge. Once you hit your max stable multi, you can't really overclock any more from there.

My 2500k does 5Ghz with my Hyper 212+ w/ Push-Pull.

A little too hot for my liking though, might need to invest in a WC kit.

Most 2600k's only oc to 5ghz if you raise the vcore to obscenely high levels. You need to win the silicon lottery, in other words - my SB only oc's to 5ghz at 1.45 vcore which obviously isn't desirable.

The 2700k is higher binned so it should be able to oc to 5ghz at a more reasonable vcore
