Sandy or Ivy?

[VtPC83]

Folks,

I'm building a new system this summer and plan on overclocking it using a 212 Evo or equiv. My question is; is it worth getting an i5 2500k and overclocking it to ~4.4 or getting an i5 3570k and overclocking that to ~4.2?

I understand Ivy's are more difficult to overclock and I wouldn't be looking for a huge overclock but I would like something. The pricing difference is only ~$25 so I just wanted to know what the consensus is? I would be getting a Z77 board.

Thanks

Ivy gives PCI3 support and consumes less power.
Although it runs a bit hotter compared to Sandy.
I'll quote another user (cmdrdredd)
Not to mention IB at the same clockspeed is faster than SB. If I remember right, a 4.2Ghz 3570k is about the same as a 4.4Ghz 2500k

Ivy. You won't have the begging rights when it comes to overclocks, but you'll have the faster (and more future-proof) machine.

As I understand it the IB heat issues dont start happening until you try to break through the 4.5/4.6 thresh hold so if 4.2-4.4 is all you are looking to do then definitely go IB.

Well, IB starts creating more heat compared to Sandy as soon as you start increasing the voltage. Depends on the particular chip how far you get on stock volts, and how much you need to increase volts to get to 4.5, for instance.

But since IB is faster than SB at stock, has a faster iGPU for backup, PCIe 3.0 and lower power consumption... the choice is pretty easy. 2500K makes sense if you get it for significantly cheaper and/or can't cut corners anywhere else

Since you are only going for a moderate OC, Ivy Bridge is definitely the way to go. Ivy Bridge does run hotter than Sandy Bridge when you increase the voltage, but the magnitude of the "problem" is way overblown. People got them and threw a bunch of volts at them, and declared that they sucked. You don't have to throw huge volts at an Ivy Bridge to get where you're looking to go.

Ivy Bridge, especially since you only want a reasonable, practical overclock.

Ivy without doubt

2600K is good enough for me. Also, I expected this because this is new technology for Intel.

Go IVY please

Newegg was running another special on ivy bridge i5 3570K. It ends today but it comes with a $20.00 gift card. So you could say it is the same price as the 2500K.

I would wait a while and see if there are any problems with Ivy Bridge.

I heard that Intel used a chaeper thermal paste inside the package of their ivy bridge processor between the processor and the metal casing on the top. i.e. you would have to take the actual processor apart to remove it.
