Reviews Word on the street for the Intel Core i5 2500K


9.0
In the PCMark Vantage full-system performance test, the Core i5-2500K earned an overall score of 10,271—not at all far behind the Core i7-2600K's result of 10,368, and surprisingly close (all things considered) to the 10,970 we saw with the Core i7-970—Intel's lower-end six-core LGA1366 CPU.

9.0
In terms of 3D performance, the detail spec changes include an upgrade from DX10 to DX10.

9.8
Boots up faster, daily things are faster, gaming results in more FPS and it clocks 10x better and higher.

9.4 Out of 10

What People Are Saying Give it to me straight

Socket Type

Thing survived a PSU short that took out a P67-UD4-B3, hit 5.2ghz long enough for a bench to finish, tho i forget which (was a year ago).
by Asbestos (Oct, 2012)
I got this CPU because I could get great overcloking off it and native SATA 3.
by Sean-Webster (Nov, 2011)
Mine happens to be one of the "worse" chips, as it requires 1.49v for 4.9GHz.
by pioneerisloud (Nov, 2011)

Socket

It is only around $225 USD, is easily overclockable, and the LGA 1155 motherboards are also inexpensive.
by carrotman (Nov, 2011)
Nothing I have done besides P95, or FAHClient can get this CPU's usage above 50.
by White-Fire (Dec, 2011)
And even though I got it for 210, you can get this chip way cheaper maybe $180, from here at OCN, or your local microcenter.
by mend0k (Dec, 2011)

Overclocking

This chip has been an absolute dream for overclocking, fairly easy to do and the performance boost you get in comparison with older platforms is mind blowing.
by munaim1 (Dec, 2011)
Pros: Fast,Solid...and overclocks like nothing you've ever seen...on air.
by PROBN4LYFE (Nov, 2011)
Pros: Great performance and overclocking ability, never really gets hot, and it is extremely cheap for how good it is.
by carrotman (Nov, 2011)

Applications

i use this for absolutely everything in between the lines of hardcore gaming and 3D modeling and this processor has never let me down.
by shadowhero18 (May, 2012)
It's cheap and crushes any game you throw at it.
by CaptainIntel (Jan, 2012)
The integrated video may not be tops, but otherwise it's currently hard to do much better than this Editors' Choice–worthy CPU if you're building a media-minded or family-focused system.
by PCMag (Apr, 2011)

Gaming

Although it doesn't HT, and is "just" a quad core, its not like games need anything more, which makes this the perfect gaming chip.
by mend0k (Dec, 2011)
Our recommendation for the Core i5-2500K in this department remains what we determined with the Core i7-2600K: Add a discrete video card if you have even the slightest interest in playing 3D games on your Sandy Bridge system.
by PCMag (Apr, 2011)
While people who get hexa or even octa core processors for gaming just waste their money and waste energy powering up those extra cores.
by mend0k (Dec, 2011)
