Intel i5-3570k vs i5-4670k

I am planning to build my very first custom computer! But I need help deciding between which processor to use :) 

I have narrowed it down to either an Ivy Bridge i5-3570k or the new Haswell i5-4670k. I plan to over clock on either CPU. I am still unsure of the benefits of moving to Haswell, but it would be nice to stay current - especially with a new build. I want to keep my build future proof, but if the Ivy Bridge can last long enough, then it doesn't matter to me. It seems like a 50/50 preference between the two processors on these forums.

I am planning to use my computer for mainly gaming, programming, and Adobe Creative Suite.

So the options would be as follows:

Ivy Bridge

There's a small performance difference between Haswell and IB. However Haswell has a reputation for being harder to OC than IB CPUs. Of course how well any particular CPU overclocks mostly comes down to luck of the draw, but you would be more likely to get a CPU that is better for overclocking if you choose Ivy Bridge than if you choose Haswell.

For that reason I'm leaning toward recommending the Ivy Bridge. You save some money and you're less likely to end up with a CPU that won't cooperate when you overclock it. However it's not a big deal either way so I wouldn't worry too much about making the right/wrong choice.

haswell is slightly faster per clock, so go with that. they both oc about the same. Realistically you wont notice the difference, and intel aren't likely to release a more powerful processor for either socket (apart from the current i7's), so both upgrade paths are more or less dead ends.

How much easier would over-clocking the Ivy Bridge be? And the Haswell socket size would only take advantage of the upcoming Broadwell, correct? If so, I am not interested in upgrading so quickly to the new chips. The Ivy Bridge would suffice for me, I think. :)

When I say Ivy Bridge is easier to overclock, I mean that you are more likely to get a CPU that is capable of high overclocks with less voltage. The process of overclocking is the same for both Ivy Bridge and Haswell. It's just that with Haswell you may need to up your voltages more to achieve certain clock speeds and thus would also need a better cooling solution to handle the extra heat.

As for chipsets I believe the word on the street is that Broadwell, although it is still an LGA1150 socket CPU, will require the yet-to-be-released Intel 9-series chipset (currently Haswell runs on 8-series chipsets). So even if you do go with Haswell now, you will still not be able to upgrade to Broadwell with the same motherboard.

Would my current cooling system be sufficient for either chip if I overclock them? So I guess it comes down to a $6 difference in the chips and the luck of the draw for overclocking if I go for the Haswell.

That cooling system is very good, probably one of the best air coolers out there in terms of performance. It has about the same cooling effectiveness as closed-loop water cooling systems.

Would the Z77 Motherboard support everything else in my build comfortably? I will be acting on your recommendation for the Ivy Bridge chip, for it's more stable overclocks. Thank you, aznricepuff! :)

You're fine with the motherboard. No compatibility issues.
