Hello
I recently got a GTX 1060 and would like to upgrade my old AMD(phenom 1055t) cpu.
The heavy use of my PC is mostly for gaming. I play all sorts of games but I'm not an upgrdae junkie. Would be nice to use the abilities of my new card though.

At first I thought I'll get an FX-8350 to go with my board but after some research I realized that for the same price I can get a much better used haswell CPU. (for the same price of a used i5-4670 I can get a NEW fx-8350)

I have a deal for good boards H87/Z87 for around 80$. And then I can still use my old board+cpu.

My questions are:
*How much is the Haswell (4670 / 4670k) better then an overclocked fx-8350. Is it worth the trouble?

*About the Intel cpu. I can get for around the same price (~20usd difference) either one - i5 - 4670 / 4670k / 4690
If they were new I'd go with with the k version, obviously. But since it's a used CPU I need advice. Do you think it's wise to get a used cpu for overclock use. I'm guessing the k version was overclocked, as that's the reason to buy it. And the Haswell work on such high temps. How is it's life span..?

Thanks for the help :)

In gaming you'll get an immediate hit of about a third better with the Haswell even before OC at games. the 8350 is a great CPU for productivity, I still have one, but it's not much of a gamer by comparison.

CPU's either work or don't more or less and while there's no telling what the 4670K went through, I'd be inclined to buy it and take my chances so I could squeeze more "megahurts" out of it. A decent AIO coooler and 4.5Ghz will make it worthwhile even vs modern systems. The nice thing about a Haswell is you can use your old DDR3 RAM.

CPUs routinely outlast the user. As you have already experienced with your current PC it's usefulness has run its course but its heart still beats on. That's normal.

I'd choose the 4670K. If you can find a Z97 board go with the 4690K. It's still a contender these days. The 2500K is even still hanging on by an electron heavily OC'd which is why I suggest the K route. Squeeze out every last drop of value. OC "out of the used box"? Nope. Use MSI AB to check your CPU usage. With a 4690K in my system

I am looking ahead to the 1080 to replace the 970. I have been saving for a while and will continue. I did consider a CPU upgrade but have seen enough to keep my 4690K and concentrate on the GPU. 16GB RAM is recommended.

I use a 212 Evo with a second fan. These days the Cryorig H7 is what I prefer for that chip.

Great guys, thanks for the ultra quick and professional replies!

I'll go with the 4670k and a z87 :)
(and yeah, I'm going with Haswell to keep my ram)

which reminds me! I have 1.65v ram (will check later for specifics, I don't remember). Will that be an issue with the Haswell...??

About the cooling discussion, I have a great tower air cooler. I find that the price difference for a water cooler that will give better numbers is not worth the money and it's always almost better to invest on better parts then the cooler. We're always on some budget ;)

The RAM I have is 2 sticks of Kingston KHX1600C9D3B1/4GB

There is a variety of Gigabyte boards I can get; GA-Z87-HD3 is the one I wanted. But a few others GA-Z87 and if I strech my budget the GA-Z87MX-D3H
There shouldn't be any difference in the memory support between the different GA-Z87's right?

I checked the memory support list and my memory is not there :(
There are very similar ones but not that exact ones.

Ok great to know!
Thanks for all the help, will make the upgrade :)

Is there a source of information to know which RAMs will work on which board? For general info and for my assurance?

If you go to the support website for the motherboard you are looking at buying it will have a QVL or memory support document. With a Haswell type board, you will find almost everything works regardless if it's on the list or not.

But there's no comprehensive list cross matching what RAM works on what board. Sometimes Gskill will have big lists on their product page of what boards they tested the RAM with, other memory vendors don't bother usually.
