***OVERCLOCKING GUIDELINES***

- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU
- Aim to keep temperatures below 70c underload if at all possible
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

I recently purchased this chip and overclocked it to 4.5Ghz which seems to be the highest you can go and still call it Stable!! It's epic and for the money its the best by far out of the new processors coming on the market from Intel. The chip runs quite cool and has low energy consumption compared to its predecessor. Just to clarify its a quad core with 6mb "smart" cache running at 3.3 stock, be warned though if you want to overclock you must get the 2500K version NOT the standard 2500 which is locked and can't be overclocked! Even if Overclocking is not you're thing, this processor will be more than good enough running at stock speeds!

Highly Recommended!!!

Just installed one of these into my upgraded system and wow...I used a CoolerMaster EVO CPU fan and was able to overclock it from the stock 3.3GHz to 4.5GHz.

Idle temps are about 20°C and under load about 30°C. That is unreal for a 37% overclock. Completely stable and super snappy. All I need to get now is a nice SSD for my System drive and this machine will be insanely fast.

Unless you are doing a lot of heavy video editing or photo editing, I would definitely recommend this over the i7 2600K. Keep the £100 and invest in an SSD to go with your i5 2500K. You won't regret it.

The Intel i5 2500k really is an incredible CPU. For under £170 nothing else comes close. It's impressively power efficient and runs at a very reasonable temperature. Yet more importantly its performance is staggering- a genuine tour-de-force from Intel.

To start it overclocks brilliantly- a stable 5 GHz is possible with a good air cooler, whilst 4.7 or 4.8 GHz is a perfectly achievable everyday overclock, which should avoid excessively high voltages. That said you don't even need to overclock it in order to get good performance- its architecture and IPC are both brilliant and as such it offers great performance even at stock frequencies. The turbo feature is also very useful for anyone who doesn't fancy- or really need- an overclock.

Furthermore it bulldozes through applications (AMD can't hope to match it unfortunately) and is sensationally good in games. Just google 'i5 2500k reviews' and have a look at some of the benchmarks recorded. Sensational.

I remember being shocked when the i5 2500k was first released a year ago- despite costing a fraction of the price it gave the beastly £800 Intel hexacore i7 980x a decent run for its money, even managing to surpass it in less multi-threaded applications. I couldn't believe that Intel could possibly sell a £200 CPU which could match their king-of-the-hill £800 hexacore. This concept made no economic sense. And a whole year later the i5 2500k still remains the unchallenged mid-range king. The perfect trade-off between price and performance (much more of the latter). A remarkable achievement indeed. It even fares well against Intel's newest extreme hexacores (LGA 2011) which easily cost three or four times as much. The i5 2500k isn't the fastest CPU in the market (although it isn't too far off...

Bought this in 2011 and its still going strong now (2014), got it when I built my PC which was used for gaming and some design work. Multi tasks really well. Running multiple monitors and applications/games at the same time and it still benchmarks very highly.
Have had no problems running a variety of games on max settings usually around a constant 50-80 FPS. Would highly recommend.

A year and a half later still going strong, overclocked too 4.3GHz with a third party £20 fan cooler unit well under the max voltage and heat safety limit. I would push it further in the future if need be but even now I can't see any need to replace the CPU for another two years. The bottleneck is with my GPU not the CPU. This is the best future proof component I have ever purchased for a PC, I still can't get my head around what good value this was for what you get in return with a little effort and know how which is all over the internet for this CPU. Go out and get it!

I bought this quite a long time ago, and it is a kinda old CPU now, but I still really love it. Right when I bought it I also had a Gigabyte motherboard, which I soon had switched out and it will probably be a very long time before I buy Gigabyte again, because that just broke like hell and was sooo bad. But then I got an awesome ASUS motherboard to a good price right here on Amazon, OC'ed it to 4.6 GHz with my Noctua NH-D14 CPU cooler, which is so freaking awesome also. Never had any problems with it, and only running at 4.6GHz for a very long time now. If you wan't a cheap CPU that is a BEAST of an overclocker, go with this! I have coupled this with a MSI HD7870 Graphics card, and I would say it's a good price to performance match, but I doubt it would do any performance hit even if you get something like a GTX 770 or a 7970 or something else high-end :)

If you are a gamer like me then you have done your research.... Thats why you are here reading these reviews.

Buy this processor, don't bother with haswell right now they do not benchmark as well they simply use less powere.

Buy the i5 2500k or i5 2550k processor!!
