with overclocking on a hyper 212 evo as high as i can go while keeping the max temp below 60 Celsius would the 3570k then outperform the 4670 or is it still better to get the 4670

also what overclock would i get?

babernet_1, what exactly are you talking about when you mean the new features of Haswell? And it's not as though it's suddenly faster or more efficient.

Hardwaremaster, Haswell is only about 5% faster than Ivy Bridge, clock-for-clock. That means at the same clock speed, haswell is very very slightly faster. If you have Ivy Bridge running at 4.4GHz (easily doable) vs a Haswell chip at 3.4GHz?

Yeah, there's simply going to be no contest there. The chip that can overclock wins.

There are a few new instruction sets for Haswell (which I regrettably can't name), but I agree that they won't suddenly become the standard.

Also I'm not sure why you're comparing an OC of 4.4 on an IB to a base clock (not turbo) of a Haswell. It would be Ivy 4.4 against Haswell 3.8 + around 200-300MHz based on the average 5-10% increase. So it would essentially be Haswell 4.0-4.1 against a 4.4 IB. Not to mention you'd need a more expensive Z87 board for the IB, and possibly better cooling. I'd personally take the locked 4670. However in raw performance, the IB would be slightly better if you're willing to spend more, I just don't see why you would.

The Haswell has the following:

Wider core: fourth ALU, third AGU, second branch prediction unit, deeper buffers, higher cache bandwidth, improved front-end and memory controller

New instructions[22] (HNI, includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, LZCNT and FMA3 support)

The instruction decode queue, which holds instructions after they have been decoded, is no longer statically partitioned between the two threads that each core can service.[18]

Now when you looked at the initial reviews of the 4670K, the speed was around 5% or so faster, clock for clock, and almost insignificant amount. However, it does amount to about 200MHz more clock speed. However, I saw some recent comparisons of the 4670K vs 3570K and now the 4670K can be 10 to 20% faster, clock for clock, since drivers/software are now starting to use some of these new features.

Yes, a 3570k overclocked would beat a locked i5.
