I7 2600 and i5 3570

well none of these motherboards are good overclocker so I am assuming you don't want to overclock. In that case, you may consider i7 2600 because it has hyperthreading. 3570k on the other hand is a good overclocker but your b75mobo won't support it much. So its a waste.

My advice, either get the 2600

or the 3570k with a z77 motherboard if you want to overclock your cpu.

either cpu will dominate in gaming and other tasks so you will be fine either way. ht adds 25% performance in theory where IB is roughly 10% better than SB. Get the deal that saves you more money.

Goodluck!  

Do you have other options in motherboard? Im not liking the models you listed.

Those are the only options :S .. so the B75 can not increase the CPU multiplier?
The rest of the system
2 x 2 GB DDR3 kingstone ram
SAPPHIRE HD 7950 OC
XFX pro series 550w PSU

My question is about overclock-able i5 and a non overclock-able i7 so the other topic didn't help me

I wish to point out that the Ivy Bridge processor is not a good overclocker and clearly you need to read some of the reviews on the topic.

It thermally ramps quickly.
It thermally throttles above 4.3 under stock voltage.
It has a poor TIM under the IHS.
It will barely handle the stock cooler under a loght gaming load at stock settings.
It draws more power when thermally ramping above 4.3 ... dramatically so ... to the point where a 2500 or 2600K processor draws less power, does not throttle, and outperforms it markedky with a decent cooler.

So if your looking for a good gaming cpu for the money it doesn't stack up.

This is for a gaming build?

Can you get a Core i5-3450 or Core i5-3550 to match up with that Gigabyte B75 and save some money that way?
No sense in play extra for the K model.

Even without overclocking if you don't stick a decent cooler on it your will be disappointed as it thermally ramps and then throttles.

@ REYNOD;
Are you seeing any thermal throttling at stock clocks on the stock coolers?
I hadn't seen any of that yet.

core i5-3550 won't save me much money so it doesn't matter if its is k or non k for the ivy bridge
Now I am think of 2 options
1- get the 2600 and sacrifice the PCIE 3 which I don't know if it will help in the future or not also with H61 I am getting only 2 ram slots
2- get the 3570K and benefit from PCIE 3 which have no effect atm and 4 ram sticks also I will be able to overclock a bit like 3.8 GHz
I hope u understand my point guys please need advice going to buy in 4 hours  

Is the i5-2500 (non-k) an option with the Gigabyte H61. How much would that save you?

Gigabyte B75M-D3V motherboard will let you overclock. That gives you the better all-round gaming CPU with the other hardware staying the same.

Will be a good match with either CPU/MB combo.

What do you have for a case?

we only have The 2500 k in my country and will save me some but I am afraid to get it as the two other options are tempting newer technology/overclocking/2-10% better performance
and on the other hand the 2600 which offers the hyberthreading

My case

No, i will stick to the stock cooler as My budget is extremely limited but may be in the far future i will get a better cooler

Good lookin' case.
You might want to think about another case fan when you get some spare change together.

No problem there.
Just watch your temps carefully, the stock cooler might not let you reach your OC goal.

A good strategy would be use the i5-3570K at stock with the HD 7950 graphics card. When it's time for a mid-life upgrade to a new more powerful GPU, get an aftermarket CPU cooler as well and overclock the CPU.
Get a CPU/GPU performance boost.

so as a final answer I go for the Gigabyte B75 + intel core i5 3570K for my gaming reg?

In your position, on a budget with limited choices, I'd chose that option myself.

Thx WR2 U really helped me a lot

Let us know how it works out.
You can do some testing on overclocking - see how things work.
I'm thinking you'll get better performance with some video card overclocking than with CPU OC's.

Here is a Step-by-Step Guide to Building a PC

Look over the forum's "System won't boot" checklist to see some of the common build errors and how to avoid them.

-> The usual advice; read the manual / install guide; look at the parts, read the manual again and if everything makes sense and looks right - then go ahead with the install.

While you're waiting for delivery you can download the online version of the motherboard manual and start getting familiar with it. Same for the other parts you want to order if they have install guides or manuals available.

I don't know what to say WR2 your perfect reply leave me nothing to ask about ... Thanks man

Well I caned a 3570 for an hour with a stock cooler and it went as hight as 65 C ... so prime would have pushed it higher I guess.

Ambient was 19C.

You do the maths.

I'd imagine it was throttling at times but I didn't check.

Yes the cooler was attached properly and I burned it in ... idle at around 30C.

It throttled when I lifted the multi to 40 ... stock voltage.

I didn't post on the basis of other reviews ... but my own experience.


The kid we built the PC for is pretty happy (I didn't chose the parts) but he now needs to cough up some extra cash for a decent cooler ... for a stock CPU that is pretty poor.

Reminds me of the Prescotts and the early D's.

In fact I should have fished out an old cooler from one of those and stuck it on it ... alas that meant looking through boxes of old stuff.

supersonic good luck with your purchase and let us know how it goes.

WR2 is a wise adviser !!
