I am getting a MSI Z68A-G43 Mobo and i cant decide between a sandybridge 2500k or a Ivybridge 3570k I will be using 2x Sapphire radeon 6870 GDDR5.

Can anyone help me choose the best cpu for what i have, many thanks.

Why get a Z68 motherboard? Z77 gets you a fair bit of extra features for about $10.

Also, either of those CPUs is more than enough for those cards.

Use google, theres probably 5 million answers to this question, one of which we answered a few hours ago:

Performance difference between the Sandy Bridge and Ivy Bridge is 3%. For 3% I would rather have much cooler temps. Intel's next chip series will have significant performance increases based on the Ivy Bridge technology.

Just wanted to add: I just finished my 3570K, and with a hyper 212 evo, I'm sitting @ 4400 without ever touching the Vcore or turbo voltage. So stock voltage 3570K, and I'm at 4.4.

The moment I go to 4.5, I get immediate BSOD, and need to add voltage. It also makes my ram a little unstable. I'll push it later, right now doing a 5 hour prime 95 run.



I dont know how it is with the 3570K, but with the 2500k @ 4.5 is finiky. Its hit or miss, and alot of people have issues (including me) hitting a stable 4.5. Your best bet would be to back down to 4.4 or bump up to 4.6 and see what happens. My 4.5 was taking 1.38v to stablize (sorta), but 4.6 only took me 1.328 (I am very confident in its stability).

i was told that the z68 was pratically the same as z77 but cheaper, is ivy better than sandybridge or they the same?

Depending on the use case, Ivy Bridge has a 5%-8% lead over Sandy Bridge. IVB has heat issues when overclocking, so you'll typically need to spend more on cooling if you plan to overclock IVB.

And no, Z68 is not just a cheaper Z77. The newer Z77 chipset supports PCIe 3.0, Virtu MVP a couple other things nobody really cares about and typically will have more USB 3.0 ports and more SATA III ports.

I don't think it's worth giving all that up to save $10.

So i will get ivybridge 2570k cpu and a msi z77a-g43 mobo along with 8gb ram and 750 watt 80+ bronze psu with 2x sapphire 6870 will that be a good set up?

I basically told you all of that in the thread in the Motherboards section. :lol:  And yes, that's a very nice setup.
