As my CPU is nearly 5 years old I was looking into upgrading it to Skylake but was surprised at the lack of performance increase (i5 2500K vs i5 6600K) I would gain from this.

Starting to think I am better off overclocking my i5 2500 instead. I did actually have a quick try at this a few months ago but with no success and gave up. Thought I would try again but getting some expert (ie overclockers forums) this time.

My motherboard is GIGABYTE GA-Z68MA-D2H-B3, I have no idea how overclocking friendly this is as wasn't considering this when I bought it. Also my RAM is Kingston HyperX Blu KHX1333C9D3B1K2/8G, 2x4GB.

My reason for wanting a CPU performance boost is that I have an Oculus Rift and although I have a 1070GTX GPU it appears the CPU is holding it back. Also running a lot of emulators lately like Dolphin and again the CPU is struggling.

Can I get a noticeable performance boost while keeping my system stable? Do I need to upgrade from the stock CPU cooler?
 
Thanks, will look into a better air cooler (not interested in water cooling) and then come back. In the meantime have started reading the thread "Beginners Guide to Overclocking"
 
Before fitting the new heatsink thought I would get some baseline temperature readings.

After booting and just idling the temp was 65, light use would go straight away up to about 72-75, under load (game or Prime95) would almost immediately go to 98 and just stay there. Noticed the CPU multiplier would never go above x16 for a core speed of only 1600 MHz. So I'm guess because the temps were running so high that it was throttling back?
 
New heatsink installed, temps mid thirties idling and high forties under load.

Now I want to start pushing up the clock speed, what settings do i adjust? All the guides I read say to increase the CPU Clock Ratio and then increase the voltage if unstable, which Voltage setting do I change? The Dynamic Vcore(DVID) option has auto, normal and then plus or minus incremental amounts....
