The CPU King,
This review is from: Intel Sandybridge i5-2500K Unlocked Core i5 Quad-Core Processor (3.30GHz, 6MB Cache, Socket 1155) (Accessory)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...), yet it offers by far the best value for money.
I used around about twelve of these brilliant CPUs in 2011- I used them in every single rig I made, for myself, for friends and for family- all were centred around the black magic of the i5 2500k.
So there you have it- as 2012 commences it appears there still isn't any worthy challenger to the i5 2500k. Someone bring me a bucket- I'm going to need a whole lot more of these :D

How did you get it to "stable" 5Ghz OC?? - Just on air its not practical, but on an expensive 'water chilled cooler' YES! it is, tho, never witnessed it done on air without the voltages turned away to an unstable point. even 4.7 and 4.8Ghz what do you recommend to cool that with, for a 24/7 overclock... best I can do is 4.6Ghz, and that's not easy, depends on individual headroom.
A reply would be nice. cheers!
if you fail to reply I will just see your review for what it is, "fiction"....
oh! also what motherboard did you use? & what voltages did you play with.?

i am not the author, but i am sitting on a stable 4.8ghz overclock right now, on air. hyper evo 212 is the cooler. and i have a p8z68 vlx mobo.
i went straight to 5ghz on the day i bought the cpu, and it crashed after an hour. i then went back down to 4.5 and worked my way up to 4.8, which is where i am now. havent even tried 4.9, and could probably manage a stable 5ghz. if not, i could up the voltage. my tempts are 55-60 under full load.
it isnt fiction.

Sorry about the really late reply, I don't often look at comments (evidently).
When I was first overclocking my i5 2500k I pushed it up to 5GHZ (with a voltage of something like 1.48V- certainly not a safe long term voltage) and ran stability tests for a couple of hours. It proved stable, but the voltage and temps were far too high to use every day, so I dialled it down. These sorts of chips vary in quality- in all truth I probably got lucky. My motherboard at the time was the Asus P8P67 I believe, and the (air) cooler was a Noctua NH-D14- not exactly the stock cooler :D
It's worth noting that as I write this comment (June 2012), the i5 2500k has been bettered- the value king is now the i5 3570K (Ivy Bridge).
