i7 2600k OC to 4.5 GHZ vs i7 3770 non K. Which is better? Both of these parts are for sale here on my area and i wanna know which is better on the long run.

Which means exactly nothing. With a 60Hz monitor it does not make any difference whatsoever if you get maximum 300fps with the 2600k or 100fps with the 3770. Maximum fps is for benchmarks, so it doesn't matter if the 2600k is faster. The only thing that matters is minimum fps, keeping it beyond 60fps is preferable, which either cpu is capable of, and with any dips below 60fps, to say 40fps, the 20% faster cpu will be 8fps ahead. Which really doesn't amount to much at all, especially if the holdup is more gpu than cpu related bringing that 8fps down or even equal.
OC really does not affect most games at all. Rendering yes, Autocad yes, games not really.

You've got a cpu made 2011-2013 that's known to have been under OC of questionable...

The 2600k at 4.5 will be faster by around 20% but will consume a fair bit more electricity to get there. The 3770 compared to even the non-overclocked 2600k uses less electricity per instruction. I'd go for the 2600k.
When you get the 2600k, make sure it comes with a good motherboard and a very good cooler.

Bunch of crap. The z77 boards used by the Ivy-Bridge cpus are quite superior to the z68 used by Sandy Bridge. You are also assuming that op has much of a choice in those lga1155 mobo's, chances are good it's easier and cheaper to find a Z77 than a non OC board. This is not to mention the differences between legacy and uefi bios, as the Ivy-Bridge were the first to really start using the newer standard widespread. You also assume that the 2600k will actually OC to 4.5GHz, and there's not been any OC abuse in its past that could impact its usable lifetime.

I'd go for the 3770. Regardless of mobo choice, it's the better option. It's fast enough to play anything, has a stable past, chances of abuse are slim, it offers options that the Sandy cpus don't.

where did you get the information that it is a z77 motheboard ? he said the i7 3770 is a non K which means it is not likely with a Z77 motherboard at all.

had it been 3770K then yes you are right , but this system is only i7 3770 non K and it could be coupled with a very cheap B75 grade motherboard or even H61 which also supports i7 3770 non k ..

now if you are saying that an H61 motherboard is better than Z68 then you know nothing about that Era ...

you are wrong about "get i7 3770 non k regardles of motherboad" because even H61 motherboards are cmpatible with ivybridge CPU

You are wrong

That comparison is at stock speed . NOT Overclocked i7 2600K

Over clocked i7 2600K @4.5 is ALOT faster than i7 3770 more than 25% faster

you are comparing 3.4 Ghz 2600K vs 3.4 Ghz 3770

not 4.5 Ghz 2600K VS 3.4 Ghz 3770 , 1.1 GHZ MORE !!!!

we are talking at least 25% more speed here.

And Ivy-Bridge had @10% faster IPC (instructions per clock) than Sandy-Bridge. Combined with the turbo speed of 3.8GHz (not the base clock of 3.4GHz, the OC being a set value and not open to turbo), 3.8 x15% = 4.37GHz equivalent to a Sandy. Compared to a 4.5GHz OC, that's serious chump change. Basically close enough to be considered equitable as far as speeds of processes going through a cpu. In a word, irrelevant.

Oh. You forgot about the turbo. Oh, you forgot Intels 'tick-tock' bumps with every new release. You cannot directly compare actual clock for clock numbers across generations, doesn't work. 3.4GHz Sandy-Bridge is not the same as 3.4GHz Ivy, or Haswell or kabylake, nor is 4.5GHz. An i7-4790k at 4.5GHz is far faster and stronger than a Sandy-Bridge i7-2600k at 4.5GHz.

your 3.8 ghz Turbo is not all cores ...

are you saying that Turbo is all cores ? and you cant 10% the turbo speed because it is not all cores and will not work Turbo all time.

2600K @ 4.5 ghz is all cores 4.5Ghz actually can reach 4.8Ghz as well.

you first made a mistake about "choose any motherboard" assuming h61 motherboards dont work with 3770 ,

and now you are talking about Turbo mode out of context. not only that you multiply 15% with fake turbo number as well while first talking about 10% ...

2600K @4.5 to 4.8 OC ALL Cores is FASTER than your i7 3770 non k

actually 2600K is one of the best overclock able CPU ever made.

as a reminder , i7 3770 all cores Turbo is 3700 MHz (4 cores)

2600K is faster what ever you say

being 4.5Ghz OC or 4.8 Ghz OC all four cores .

and your 10% is nothing here. (3.7 x 1.1 = 4Ghz)

You are being abusive and you are wrong. The 3770 is around 9% faster at stock. A 32% overclock dramatically tips the performance to the 2600k. It has a net effect of slightly more than the 20% I mentioned above. I used very similar systems to this side by side for a long time. I had a 2500k running at 4.5ghz and a 3770k where I left it stock. I was going to OC it when it no longer suited my needs, but in the end I downstreamed both to my boys and bought a 5930k instead. With three gaming age boys, there is always a demand for more hardware. Before I gave them away, I used the 2500k as a render box and the 3770k as a gaming box, surfing, work and whatever. You can be certain I compared render speeds several times before I settled on which one to use for what.
In this case we have the 2600k not my 2500k. The 2600k has a larger L3 cache. And I had the 3770k not the lower end 3770. I'd bet I also had a fancier motherboard than the 3770 comes with. Even so the 2500k beat the 3770k. There is no way the 3770 is going to be close to a 4.5ghz 3770.

#1: Let's keep it civil here.

There is simply no right or wrong answer and the OP has not given enough guidance on what other parts he may or may not have to make assumptions about that.

I have both an OC'd 2600K on a Z68 and a non-K 3770 on a comparable ASUS board among the many machines at my house and both have good qualities, and both are still useful for their current purpose. Price difference, board included if any, and trust in the source are also all important in buying used parts.

Regarding the userbenchmark.com comparison, the 2600K is not at stock speed. It is the average of all users who submitted a benchmark. So that could be under-clocks, stock-clocks, and over-clocks. Though it does say Worst Bench: 3.4GHz, Best Bench: 4.8GHz It's just an average, likely somewhere past stock clock.

Well, i have a friend who actually has both of these cpus and he wants me to choose. I can get the i7 2600k + z77 mobo for $200 while i can get the i7 3770 and h61 mobo for $170. If i choose the i7 2600k? What's the Average OC for it? and would it significantly beat the i7 3770 or would it just be around 5-10% difference?

These will be used cpus. As said, the i7-2600k is one of the best OC cpus Intel ever made, and there are many builds showing a 4.8GHz OC successfully. In an ordinary world, that'd be great, 4.5GHz should be easy, no stress on cpu etc. But that assumes there's a knowledge of the cpus history. There's a solid chance that particular cpu has spent years at max vcore 4.9GHz and has already started cascade decay to the extent that 4.5GHz is now the highest stable OC possible.

Op asked for a cpu that'd be better in the long run. The chances of the 3770 being good for the next 5 years are very good. The chances of the 2600k being good for the next 5 years are hit or miss. While the 2600k @ 4.5GHz might show some small benefit now, that's not to say it will next week, next year, tomorrow. I don't see it as a good long-term prospect, the clock speed benefit not being enough to warrant spending the cash. It's a 4-6 yr old cpu that in my mind equates to a rental car. It might have been treated nice, or might have been used in 'Dukes of Hazzard' by a teenager..

So for longetivity, the i7 3770 is safer right?

I would agree that yes the i7-3770 would last longer.

both are old . longevity is the same. plus check which motherboard comes with the system... there is a huge difference between a H61 Motherboard and a Z68 motherboard.

2600K is ALOT FASTER than 3770 non K

OC really does not affect most games at all. Rendering yes, Autocad yes, games not really.

You've got a cpu made 2011-2013 that's known to have been under OC of questionable amount, vrs cpu made middle of 2012-december 2014 that's never seen OC abuse, has improved bios, instruction sets, architecture, doesn't need anything more than the stock cooler. For all intents and purposes, the 3770 is the more reliable cpu, that will do the job just fine, regardless of the fact that it looses a few fps. The ability to OC an intel cpu has been nothing more than a hobby. It's next to useless as far as games go as reliance is on the gpu not the cpu primarily.

You can game at 4k just fine with an i5-8400 and 1080ti, you don't need a i7-7700k just because it'll get 5.0GHz. For example.

Difference between a h61 and z77 is the ability to OC and the power phases etc included in that. The z77 might have slightly better audio codecs, which means nothing to a pair of headphones or pc speakers the only ppl who have any use for top rated audio are audiophiles and other related sound junkies. Otherwise H and Z boards are almost identical in setup and connectivity, even to the point of 8+8 pcie for sli etc. I own an Asus z77 (p8z77-v LE) that's next to useless. Won't do an OC higher than 4.3, has minimal heatsinking on VRM's, 16+4(2) pcie x16 and audio codecs lower than some B boards. The ability to OC doesn't make it a better board by any means. Performance on any series of mobo's is almost identical with respect to consumer grade boards. You have to move to the enthusiast boards like msi mpower or Asus maximus to see any difference, so for the most part, No, there's extremely little difference between an H61, Z68 or even Z77 mobo.
