    From what I have ready, Ivy Bridge runs hotter, and you should not even consider overclocking without some serious cooling. Like, spend at very least a couple hundred of dollars on cooling.

    So in this case, say you had a 3770K and you wanted to overclock. You would need to spend another say $300 on cooling or risk permanently damaging the card from overheating.

    In the alternative scenario, consider Sandy Bridge. Since it runs cooler, you could safely overclock quite a bit with at most a $40 fan cooler like this: COOLER MASTER Hyper 212 EVO RR-212E-20PK-R2 Contin...

    Now let's look at overall costs:

    2600K: $320 (new) + $35 cooler
    = $355 total

    3770K: $320 (new) + $300 to $600 in cooling
    = $620 to $920 total

    Benchmarks rate the 3770K to perform somewhere around 3% to 7% better than the 2600K. But if these prices and analysis are correct, then by overclocking, the 2600K could way surpass the 3770K at the same cost, considering cooling.

    So, for you experts, what do you think about this? Do you have anything to add or clarify?
    Perhaps you can shed some light on this issue?

    The issue is your ridiculous and completely unbalance cooling requirements. With $300+ spend in cooling, you must be thinking custom loop and attempting to reach well over 5.0 GHz, both of which is completely unneeded for daily use and/or gaming.

    On the flip side, the 2600K will not be overclocked very far with a $35 cooler of any kind and you will be limited to 4.4 GHz to maintain stability. So why are you shortchanging the 2600K?

    The 3770K performance is more like 7% to 15% faster at the same clock speed to my knowledge. While it does run a bit hotter, keeping them in comparable temperature range, you will be spending like $75 on cooling, not $300. Is it worth the extra $40? Yes, yes it is.

    i think your overheating :p any $40-60 cooler can take a IB to 4.0 ghz with ease

    Just as a note a good motherboard will also make or break overclocking. I have a p67 sabertooth and the overclocking is rather subpar so if you don't spend good money on a motherboard don't expect any great overclocks.

    Ok, this directly answers my concerns.

    As far as exaggerating the differences, it was for emphasis. But you understood what I was asking, and excellent answer.

    Combine that with Sandy Bridge incompatibility with PCE-e (for ATI since NVIDIA released a patch for this), and the Ivy-bridge is still the winner.


    I've got a z77 motherboard. Check my build thread for full details if you're interested.

    You can see the difference (between 2.0 x16 and 3.0 x16) is minimal. 1-2%

    No, I saw that. I was looking at the 680 not the 7970.

    680 is 1-8%, but 7970 is 1-4%

    88% is at x4...compare PCI-e 3.0 x16 to PCI-e 2.0 x16 = 1%

    The most expensive(powerful) cards require the most bandwidth, for slower cards the difference would smaller or there would be no difference between 8x to 16x at all.

    Odd. I have had 2 and both have overclocked quite well. I mean I have never attempted any extreme OC but does 4.6 with little effort.

    Sabertooth motherboard are high-end and should OC well,either you are missings a settings or two,or you got a bad cpu sample.

    I run my i5 2500k at 4.4 with a 212 evo. Prime hits 71c 3dmark11 hits 68c. I would still rather have a IB i5-3570K

    Yet again we have a thread started by vawrvawerawe which includes massive ridiculousness and a failure to comprehend a simple graph.

    Buy a 3770K and buy an H60/70/80.

    My 3770K is at 4.4GHz @ 1.185v on a Hyper 212 EVO and 2 Cougar 1200RPM fans in push-pull. Maximum temperature under IntelBurnTest is 90-92c on core 1 and the package after twisting the center bolt on the mounting bracket clockwise all the way. 4.5GHz is unstable even with 1.225v and 4.6 hangs at UEFI.

    I would wager my setup could get lower temps and doesn't look like the bronze man pooped it out.

    I've got a 3770k at 4.5 ghz, 1.23v... Cooled by a 212 EVO with Scythe GT AP-30s in push/pull... maxes out at 75C (10 passes of IBT)... $300 to cool a 3770k? With a custom loop maybe... :)
