Hi guys my cousin wants to buy a new pc for gaming. We only need to choose the processor, in the store both at the same price.

what do you recommend?

I would recommend getting the Ivy Bridge i5 3570K (consumes less power and slightly more efficient per clock than the i5 2500K) if you aren't going for insane OCing.

The Fx 8150 is overpriced and underpowered. It barely comes close to the i5 2500K in heavily threaded tasks and face-plants upon lightly threaded tasks such as almost all games.

If you really want AMD, you can wait for Piledriver, but be warned that new CPUs aren't expected by AMD to compete against Intel's IB processors in performance. Your best hope is that they have better value per performance.

Grab the i5 2500k with a powerful aftermarket cooler, up the multi to 47X @ 1.335vcore and you got a 4.7Ghz overclock!!

Folks, he didn't specify if he wanted OCing, and even if he did want OCing, the 2500k is only good for high OCing (past 4.5 GHz).

Firstly, I am not an Intel or AMD fanboy -- so keep that in mind.

Buy a 2500k

1) For gaming, the difference between the two are negligible, as most games rely on GPU power, nevertheless, the 2500k shows improvements in games that are CPU -intensive because as far as raw CPU capabilites go, Intel beats out AMD by a pretty good margin.

2) If you are a grahics designer, 3D modeler, AutoCADer - for basically any CPU-intensive application, the 2500k beats out the AMD FX once more.

Although AMD put lots of emphasis on thi new 8 core stuff, the performance does not translate directly for two reasons.

A. Each of AMD's 8 "cores" are not allowed the same amount of resources as each of Intel's 4 cores.
AMD didn't put 8 full cores, instead, they have two "modules" each sporting 4 lesser powered cores that share resources, thus, 8 core. The trade off is that you get less performance per core and that is very noticeable in most programs.

B. Most programs are coded for 4 cores, so although you are getting 8 "cores" from AMD, not all of them will be used to their upmost potential, because the program is not written to distribute the workload between 8 cores -- few programs are nowadays.

Benchmarks have showed FX processors paling in comparison to even the older AMD 6 core 1090t, a generation before. Furthermore, benchmarks have showed the 2500k wiping the floor, basically, with the FX.

So in conclusion--

If you are a gamer looking to buy a good CPU to play the latest games, opt for 2500k

If you need a high-quality, high performance CPU - opt for 2500k.

At the same price-point, it becomes common sense.

Your point is what he didn't say he could get a ivy cpu for same price nor was it part of his question.

Do not under any circumstances get the 8150 for gaming. I bought one and it sucks monkey balls compared to a 3770k which I have now. So yeah get the 2500k I know at some stores you can catch a deal for a 3570k for the same price or cheaper than a 2500k.

No doubt about it price to performance the I5 2500k can't be beaten for in gaming. It's faster than anything AMD has out there right now and can pretty easily be overclcocked to 4.5 GHz with a good aftermarket cooler.
