    Ordering full PC in three days, but then thought what Generation of I5 do i want?
    I am mainly using this computer for gaming and intend on overclocking, and I am not using liquid cooling (but my case has many fans (CM-Storm Scout).
    If you would advice me to go with the 3570k (Ivy), what series of motherboard do I want? A z77 or a z68 gen3.
    It is only a matter of 25$ so price is not a factor.
    Build:
    Gtx 670 ftw 2gb
    Intel I5 (2nd or 3rd gen)
    SSD- corsair force gt 120gb
    8gb corsair vengence
    tx650w corsair
    Windows home premium
    WD Caviar Black 500 gb
    Samsung 22x DVD burner
    Cooler Master hyper 212 evo
    CM-Storm Scout case

    Thanks,
    Walrus

    If the 2500k is cheaper then go for that. they easily overclock to 4.8Ghz or & even higher.

    Since you are getting a new system, I suggest going for a z77 board.

    as far as Gen3 is concerned it makes very little difference (about 1% at best) but like i say, If you are building a new system, theres no reason not to go with a hardware that supports all these new features even if some of them are a bit of a gimmick

    Go for the newer one, the small difference in price makes it a worthy step up

    Either is fine, but I lean towards 2500K because its cheaper.

    If you intend on overclocking but NOT going water, then Sandy Bridge is the better choice. Ivy chips get hotter when overclocked, but are also a bit faster than Sandy chips at the same clock speed(by about 300MHz. i.e. a 4GHz Ivy will perform nearly the same as a comparable Sandy at 4.3GHz).
    As far as board goes, Z77, hands down. It's newer tech, has more features, and will allow you to upgrade to Ivy down the road should you choose to.
    Really, you can't go wrong with either processor, just make sure you go with a Z77 board;)

    Rather than go into detail, here's the big picture.

    Ivy Bridge:
    Better instructions per cycle (IPC), so similar clocks to SB will yield better performance.
    Poorer thermal transfer, due to Intel manufacturing choices.
    PCI-e 3.0 for future graphics cards, but little benefit with current generation.
    More integrated controllers, specifically USB 3.0.


    Sandy Bridge:
    Lower, in general, pricing due to being "old."
    Higher overclocks, in general, are possible.
    "Only" PCI-e 2.0, but no real influence on the current generation of graphics cards.
    Less integrated peripherals, generally leading to slightly higher motherboard prices.


    If I were buying:
    Pair a 2500k with a Z77 based board. In the future, you can switch to an IB processor, while getting a cheap and excellent overclocker now.

    Additionally, read the Asus direct copper 2 review on this site. It may be worth getting, in lieu of what you have said. If it isn't, then at least it's something to consider.

    That's handled by the chipset, not processor. Z77 has an integrated USB3.0 controller, whereas Z68 did not.

    Thank you for the help
    One more thing, when someone is saying that they have to "flash bio" for ivy bridge what does that mean?

    Flash bios, you only need to do that for older 6x boards which didn't have Ivy Bridge support right out of their ancient boxes, the updated bios has the profiles of the new Ivy Bridge chips

    Yes, you will not need to flash your BIOS to get the profiles of the Ivy Bridge processors.

    :laugh: Tell that to Crazyeyesreaper, whose 2500K reached 4.4 GHz only.


    :eek:

    Seconded.

    The Gigabyte UD5H board you're looking at is great.

    Since you're not doing a water loop and it's cheaper, get the 2500k.

    "Only" 4.4Ghz. While it's a valid statement relative to the other ones it still makes me shake my head. We are kinda spoiled these days.
