hi everyone. Running x4 860k(@4.3 GHz) along with 2x r9 270x, Corsair h90 and 8 Gb ram. I think my cpu holds me back in some games( I play mostly nba2k16, sometimes metal gear solid v, bf4, far cry4).
I am thinking of upgrading it but not for crazy money so I looked at some USED options:
AMD fx8320 with good motherboard and oveclock it(if, what results we are talking about?)
i5 2500k with let's say MSI z87-gd65 gaming mobo and overclock it
i5 4570 with same mobo as above but no OCing obviously

what would be the best performance wise route? Is overclocked fx 8320 going to run games better than overclocked i5 2500k? or maybe stock i5 4570 @3.2 GHz would be the fastest . Also with AMD it's a dead end really as AM3+ is over pretty much, however, I can get fx8320 with Asus sabertooth fx990 r2.0(which is one of the best mobos) much cheaper than mentioned i5's with any mobo.

Or maybe gains would be so little that it is not worth replacing x4 860k?

If you are planning on the Intel Haswell CPU, either the Z87 or Z97 will be fine. In fact since you won't be OC'ing, there's no real need to go with the Zxx chipset. Wikipedia has a good description of the various Haswell compatible chipsets and what their differences are. https://en.wikipedia.org/wiki/LGA_1150

The Haswell i5 will be a great CPU for any game and any gfx card no matter its size.

The Z87 board is a 1150 socket. The i5-2500K is an 1155 socket CPU. So that combo is out.
Either of the other two choices are great, although the 8-series chipset has been superseded by the 9-series now for the 1150 socket. The Intel i5-4750 route is faster obviously than the FX-8xxx.
The i5-2500K and the FX-8320 OC'ed will be about the same in gaming performance. I had an i5-2500K and an FX-8350 and am going by my Firestrike scores I got using my R9-290X with those CPUs. The i5-2500K garnered a slightly higher score, but for all practical purpose was the same in game play.

yes, I got it confused about i5 2500k, it's not an option as it's too old and mobos are quite expensive.
In almost all tests and benchmarks i5 4570 beats fx8320 badly(even if OCed to 4.5-4.7 GHz) so I think i5 is the pick for me.
Now regarding chipset...Do I really need Z97, not Z87? I won't be able to overclock anyway as it's not "k" version, are there any other performance benefits from having Z97 instead of Z87?

thx for your help. So I bought Msi Z87-GD65 board and i5 4570.
I have two Msi R9 270x gaming 4GB crossfired, won't an i5 4570 be a bottleneck? Is it a good idea to have those two cards xfired in that setup?
Also i've got 2x 4GB HyperX Savage 2400MHz. What speed I should choose for this cpu? And finally, would this cpu support another 2x 4GB of same memory( 4 sticks in total, 16 GB) and would I notice any improvements in games by going for another pair of ram?

Is this your board? http://us.msi.com/product/mb/Z87-GD65-GAMING.html#hero-specification
The i5-4570 will support dual cards of that class fine.
Natively, that CPU supports RAM speeds of DDR3-1333, DDR3-1600. It will probably be fine running the memory at a higher speed, but no guarantees. The i5 in my sig is running 1600 MHz memory. I've always been one to forgo running the memory at faster than the memory controller will support. But that's just me. Besides, memory speeds are one of the things that has the least effect on performance.

I like MSI boards. Some folks put them down, but I have had great success with them. Sometimes they are not the best OC'ers, but they are still good boards. The newer line of boards like that one are very good.

The motherboard determines the number of and (OC) speed of memory sticks. But yes, the i5 will handle populating all 4 slots on the board. You seem to be somewhat hesitant of the i5-4570. It is a top tier gaming CPU.

I don't have a big experience with Intel, always been into AMD(mostly because of price to be honest) but it's been tempting so I decided to give it a go. It's not the newest cpu and it can't be overclocked so I just wanna be 100% sure I've made a good choice. Most AMD cpus are rubbish at stock speed and only quite heavy overclocking on good motherboards make them somewhat worth to look at. Hopefully it's not the case with Intel.
thank you for your big help, once I get everything running I report back with a big smile on my face :)
