i5 2500k instead of a i5 6500? But which mainboard?

post #1 of 10
Thread Starter 
Hello,

i am currently sitting on a E5410 and i thought about buying an old core i5 2500k with a mainboard which allows some overclocking instead of a new skylake i5 6500 which only has around ~18% more performance.

Is this a reasonable idea? If so, which mainboard would you recommend?

With best regards

whatever board you are going to find is going to be used.

where are you located.

that's the best start.

Hi and thanks for your answer,

yes, the CPU will be used as well. But will it be a problem?

I am located in germany. So which price would be fair for a i5 2500k and which mainboard should i buy (which has overclocking features)?

Skylake is at least 21% faster IPC wise. and some z170 mobo (with a BIOS update) allow OC to non K CPUs

But i think Intel wants the mainboard manufacturer to release a bios update which will render that unintended feature impossible?

So you wouldn't recommend buying a i5 2500k?

If you wanna buy used get a 4790k with a Z97 mobo and DDR3 RAM and u got 99% of 6700K performance for much much less.

Sound advice. You can go with a Haswell i5 as well, nothing wrong with those chips.

Okay. I searched for a used ivy-bridge system and found a Intel Core i5-3570K + ASUS P8Z77-V LX for 200€. Is this a reasonable price?

I also searched for a 4790k and there is no one below 280€.

There's nothing wrong with the performance of a 2500K even now, but if you don't already have a motherboard that will take it, or it's not included with the deal, it's probably not worth bothering with. It's been two and a half years since any Sandy/Ivy motherboards were made, and very old motherboards tend to become unreliable.

If you want to get a used CPU to save money, get a Haswell. You can still buy new motherboards for Haswell CPU's, and performance-wise, they're not that far behind the new Skylakes, plus they can use DDR3 if you have a lot of RAM that you don't want to have to replace.

This ^^^

Get the Skylake or a used Haswell.

Today, I would rather buy a locked i5 6500 than an unlocked i5 2500k. New tech, stable, lower power draw, modern motherboard features, and similar or better performance than an overclocked 2500k apparently:
