2017 - i5-2500k is still a good processor for gaming in FullHD :P
I'm running my 2500k @4.5 GHz stable since about 6 Months (without chaning the VCore). Thermalright Macho, MSI P67A-G45.
Late :( into overclocking. Is it okay for the 2500k to run at 4.0GHz on air stable? My Current set up is 2500k, CM 212 Evo Heatsink, and z77 Asrock Extreme 4. I have been running at stock 3.3 Ghz
Exactly, not worth the upgrade. My trusty 2500k is running at 4.3ghz without breaking a sweat in games! Hopefully Skylake or Cannonflake will do better!
If you want a noticeable difference go for the 5960x, it's just 1000 bucks!
