Query i5 2500K or i5 3750K?

Have just been asked which is best for new build (see title).

I am new building and getting stuff together and have my board - Asus P8Z77-V and was intending to get the Ivy Bridge but have seen a few Googles where the Sandy Bridge comes out a tad better than the Ivy Bridge.

So now I am wondering what to do / get??

I say Ivy Bridge.
2 Reasons: native USB 3.0 support and PCI-e 3.0.

Didn't you post recently that you originally built an i5-2500 and felt it was a mistake and that you should have gone with something stronger?

Yes ignatzatsonic I did that was a build I did about a year ago now when the choice was a H67 or P67 board and as I was not intending to do any graphical stuff I thought I would get out of it cheaper. But now am kicking myself for going that way because I have been playing around a bit with graphics and want to try overclocking too.( In hindsight I wasn't thinking too bright eh?)

So I Googled SB v IB and it sort of seemed that the 2500K had the grunt and the 3750K had the graphics and not so much grunt. As I intend as does a friend who is doing a very similar build - to use a GTX 650 GPU I thought well get the CPU with the grunt as the card will take care of the graphics.

TV the current 2500 handles 3.0 USB and I am not sure what is meant by native support in the Ivy Bridge - is that better than what I have now?

I suppose the other thing that was swaying me at first towards the Ivy Bridge was the lower power consumption too.

USB 3.0 was integrated into the Sandy Bridge system boards by the manufacturers if they decided to do so. But this was an add-on system, much like a secondary SATA controller, and there were a lot of issues with performance in the system.

Ivy Bridge chipsets have USB 3.0 built in. So it is a part of the Intel system and should perform better. The only problem is the Intel chipset only allows for 2 ports.

3570K........it is an absolute beast. While SB can hit higher OC numbers ON AVERAGE, IB can reach damn near the same numbers and runs 10-15% more efficient. Basically 4.6GHz IB is equivalent to a SB clocked at 4.8GHz..........that is a basic generalization I've read on many hardware reviewer sites. The 3570K will be able to handle anything you throw at it without breaking a sweat, no question about that. Plus, you have the Z77 motherboard so you get the new technology upgrades that come with that. I know Z77 and Ivy Bridge CPU's utilize RAM more efficiently as well as USB 3.0 and PCI Express 3.0 which was mentioned earlier. Anybody that said that the 3570K doesn't have as much "grunt" as the 2500K is outside their mind. Go with the 3570K with the HD 4000 graphics, figure out how to use the 4000 graphics along with your discrete graphics card, and rock on. Should be a no-brainer since you already have the Z77 motherboard.

It sounds like a step backwards to have a Z77 board and put a Sandy Bridge chip in it, when you can get an Ivy Bridge.
From a gaming standpoint it might make sense, but in terms of having the new technology, go Ivy Bridge.

With a Z77 mobo, there is no reason whatsoever to go with a 2500K, unless you have a friend that is willing to sell it to you on the cheap.......because he has upgraded to the 3570K. If you are straight up buying a new CPU and you aren't counting every penny, get the 3570K.

Thanks everyone that explanation of the 3.0 was really what I needed to know so am going the 3570K

As it is my usual supplier has dropped the 2500K and also the 3570K price too from $245 to $233

I can honestly say from these few posts I have gained so much and again I cannot thank you folks enough

May have a look there if you don't already know it...Ivy Bridge Overclocking Guide

Choosed IB more for the HD Graphics & pci-e 3.0, than overclocking
