Worth upgrading i7 2600k to i5 6600k?

[Falexo]

Hello everyone, i've recently come to the conclusion that i want to uppgrade my gpu from dual gtx 560 ti's to a single 1060 6gb. But i currently have a i7 2600k running at 4.2 ghz and i fear that it might affect my fps negatively or even bottleneck. So my question is: is it worth the upgrade to an i5 6600k (going to be running it stock) and will i experience bottlenecking if i don't do it?
I'm pretty much only gaming so that's the most important part.
Pc specs atm:
CPU: i7 2600k 4,2 ghz
2x gtx 560 ti in SLI
16gb ddr3 ram
750w gold certified psu
Pci e 2.0
Thanks!

Hard to say, it depends on which games. A few like bf1 and witcher3 seem to benefit from ht, a lot of games don't. The 6600k edges out the 2600k stock for stock and the 6600k is only 100mhz faster at stock so most of the difference comes from ipc improvements. Your 2600k is oc'd to 4.2 but the 6600k should also be able to hit 4.2ghz easily, likely 4.5-4.7ghz.

I'm not sure why you'd run the 6600k stock when you've got the current i7 oc'd. If you want to compare the 2600k with the benefits of overclocking to a hobbled 6600k kept at stock then performance may be similar. The easiest way to check is to get the 1060, that seems to be the card you're shooting for either way. Pair it with your current setup and monitor usage and your fps, see how it games. If you're satisfied, you're good. If not then consider a cpu upgrade. Either way fps and eye candy should improve quite a bit, a 1060 is far stronger than 560's in sli. Not to mention not all games utilize sli very well and if you're playing some that don't you're reduced to a single 560's performance.

Assuming this is for gaming, I'm surprised you're even considering this upgrade. I think Synphul's link from Anandtech Bench answers your question.

Look at the GTX 980 gaming benchmarks (pretty similar performance to the 1060 you're considering). Your old 2600K holds up really well, and in some games (Shadow of Morder and GTA5), the 2600K does a much, much better job at holding the minimum frame rates at acceptable levels. My guess is that's because those games are well threaded (a sign of things to come) and the HT on the 2600K helps out when some random Window process or game related feature chews up some CPU cycles.

On top of that, we've recently had Ryzen announcements and things are looking really promising. We'll need to wait for release and proper review, of course. If your current build actually failed and you had to upgrade you'd be on the right track. But given you have a working build that's doing the job, and there's a good chance of a real CPU shake up in the next 3-4 months, upgrading now is not a good idea IMHO.

If you're looking for more performance, can you push the OC on a little harder? Most 2600Ks can get into the high 4Ghz or even to 5Ghz on decent air or AIO coolers without excessive voltage. You should be easily able to get 10% or more without breaking a sweat. If that requires a new cooler, then that's a good investment because you can move it to your new build when you decide to go that way.

Thanks guys, i think i'll keep my i7 and wait for the new CPUs. Your answers helped out alot!
