The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]

Run for years overclocked at 4.5Ghz on air. Recently bought a used i7-2600K to replace it only cuz newer games are beginning (barely) to use more threads. REALLY wanted to upgrade to a Skylake or Haswell but just doesn't make any monetary sense at all as the Sandys still perform within intimate slapping distance of their youngers. —Feb '16

overclocks well. You can get sandybridge motherboards much cheaper now too.—Feb '15

Doesnt run too hot with proper cooling. Great overclocker.

Comment 

Running at 5.1GHz 24-7 (with 0 prfor almost 3 years with two newer GTX 780s \ 16GB or 2GHz DDR3 and this thing screams...even with highest setting on newer games @4K 60Hz. The CPU is still not a bottleneck with the newer cards..I could run it at 5.3 but seems to be running significantly hotter. I'm sure I could run it at 5.3 24\7 if I upgrade my water-block and pump on my custom loop.—Feb '15

Best Overclocking cpu EVER CREATED !!!—Feb '15

Stable at 4.5GHz only Air (and very low temp); 60fps with gtx 970 in GTA V aLmost all ultra settings. Far Cry 4 just goes perfect as well as AC Unity and Project Cars; all maxed out and fluid 60. should say more about this old cpu? —Dec '15

Cost me 200 bucks back in the day. Could spend same money on a Skylake and get little or no performance increase. Massive value for money, even 5 years down the road.

Can get to 4Ghz on stock cooling and not that far off the i7's for 99% of the time. Best value cpu on the market. For normal use, no need to overclock this. Pros: Brilliant value for money, unlocked and overclockable. -- Dropped my rating due to the release of a successor the i5 3570K

Almost as good as it gets at a reasonable price, this gets my vote. Pros: Superb value for money. Superseded by the new i5-3570K

using it from 2011 it's a real pleasure for me , the best cpu i ever use till today , easy overclockable , stable at 4.2 ghz for me


Outstanding

I run my i5 2500k at 5GHz at 1.4v and its stable as can be. I use this for gaming because of arma 3's high cpu clock speed requirement for playing with over 100 players in a war server. The processor scored 102% which is great for a processor i paid $60 for on ebay.
