i5-3570k vs 15-4670k

I am unable to figure out which processor would be better. Both processors are the same price of $219, but after doing some research have learned that ivy bridge uses less power, and overclocks a good amount more than haswell. I also understand the whole 1155 socket being dead, but is possible performance loss worth the "future resistance".
Also the i7's ivy bridge and haswell are also priced the same but are $100 more than the i5. Also I have an i7-2670qm laptop so would that take care of anything I may possibly need the hyper-threading for? I appreciate the help to my indecisive self.
In addition I noticed the smaller selection of lga 1150 compatible liquid coolers and don't want to spend a lot on a watercooler.

More about : 3570k 4670k

I've seen conflicting reports on overclocking Haswell. Some review sites say that it does much better than Ivy, some say it does a little worse. I'd grab the 4670k, if I were in the market right now, to be honest. (my 2500k is doing just fine for me right now:D  )

You don't "need" Hyperthreading (per se) for anything, all it does is add extra processing power (mostly) in heavily threaded jobs. Both the 3570k and the 4670k will dust the i7-2670qm in *any* job, though it's still quite the respectable lappy CPU.

Firstly, your laptop's i7 can't even start to compete with a 3570/4670.

Now with that being said, yes the 4670s have been seing some temperature problems, thus causing OCing problems. However as you said, the 3570k socket (1155) is now dead, so you have no upgrade path. With an 1150 socket (Z87) motherboard, you'll always have the option to upgrade to the next family of 1150 CPUs.

Me personally I would go with the 4670k, simply because that upgrade path exists.

As for needing hyperthreading, unless you're an EXTREME multitasker or do video editing the extra cost for the i7 is not justified.

For the watercoolers, you don't have to watercool to over clock. However, most 1155 compatible coolers are also 1150 compatible. The Corsairs (H100/110/etc...), I believe the NZXT Krakens are, the Swift Tech H220/320. I personally recommend the Swift Tech H220. Its more expensive, but great cooling and ultra quiet. However the tubes on it can interfere with big motherboard heat sinks.

Hope this helped!

Thanks both of you for your responses. I didn't mean to sound clueless trying to compare my laptop with these lol. Just out of curiosity, how big of a difference is there in video editing between the i5 and i7. If some point along the line with the i5 I decide I want to do some video editing how would it perform? I imagine it wouldn't be horrible, but I've yet to gain sufficient knowledge on this subject. Not that I'm saying I still have interest in the i7, but I'm interested in if it's significant enough to go to an i7.

As the load optimization approaches the theoretical limits of the CPU, the performance gains in a Hyperthreaded CPU will approach ~33% over its non-Hyperthreaded equivalent. The i5 is still a great choice for casual editing/encoding/rendering.

Yes the extra 4 Virtual cores of the i7 provide a fair increase, but $100 isn't justifiable unless its heavy rendering or more than a hobby. The i5 as he stated still does a phenomenal job with casual video work.

If thinking the 1150 and Haswell keep in mind, realistically there is no upgrade path unless you'll want to run outdated hardware...next line of CPUs Broadwell have already been slipped to 2015, and when they do come out, just as with the release of Ivy bridge, there will be new mobos with a new chipset, and also running DDR4 rather than DDR3 currently in the 1150 mobos, so effectively the current 1150 is as dead as the 1155 mobos, just to clarify another misconception that seems to be popular ;)

Thanks for the info. I shall return to the forum if I have any future questions.
