Gonna build new pc in few weeks and cant decide which cpu to take and am planning to overclock it to around 4.3~4.4 Ghz.
 
Solution
From what I have heard, it's kind of hard to get the Haswell above 4.2 w/o encountering issues unless you have a very high-end cooling set-up. However, Haswell is the latest socket design, so it may carry-over for a couple of new mobo designs to come, whereas, although it oc's better, the IB is a dead socket(1155) and there will be few if any mobo improvements/variations to come.

I guess it boils down to do you want the best oc'ing set-up or is longevity/upgradability more important? If it's oc'ing, then definitely IB vs if its with the future in mind, go Haswell.

3570k,

Ivy Bridge is a lot better at overclocking, cheaper and generates a lot less heat.

If Picking the 3570k solely on Overclocking, Might want to consider

While correct on Higher Overclockability of the i5-3570, it is not a given.
1) Higher OCs are very dependent on the Individual CPU and on the MB. Not everyone hits the same higher OC for a given CPU.
2) Most likely you will get a Higher OC on the i5-3570, but to be noticable it would have to be in the order of 20% Higher. Say your i5-4670 hits 4.2, then to see the diff you would have to OC the i5-3570 to almost 5.0 Ghz. Reason A) Haswell is 5% faster @ the same clock speed + you need a 10->15 increase in CPU speed to be able to detect at the system level.

Comparing a i5-4xxxK @ 4.2 GHZ to a i5-3xxxK At Say 4.8 GHz. YES you will see a higher Benchmarks for the SB - BUT will there be a NOTICABLE difference you your day-2-day Use in REAL live programs - Probably NOT. I have an i5-2500K that I Overclocked to 4.8 GHZ and I backed it off to 4.2 GHz for this exact reason - Just not enough real world diff.

PS: In Tom's test, using an i7-4770K consistantly hit 4.6->4.7 GHx on 4 $160 Haswell B. (HSF was a $70 Air HSF) - With MID end HSF and a i5-4xxx 4.2 to -> 4.5 should be OK

Then you have to factor in the advances of the Haswell platorm vs the IB platform.
Increased Native suport for SATA III (6 GB/s) 2 vs 6
Increased USB 3 connectivity
Increased PCI-e lanes
Plus probably some unknows.
Tried to keep apples to apples so I compared a Gigabyte Z77 UD5H to a Gigabyte Z87 UD5H.
