Review my build I5 3570k

i didnt quite get that... you're saying that the z68 chipset isnt compatible with the ivy bridge unless i do a bios update?
if thats the case then why spend more money buying a z77 when i can purchase a less expensive mobo and just do an update?

and about the psu iam more worried about cpu OC than gpu

Or if not CF/SLIng:

It is Z75, so how is it not?

The importance of power phase count
Now, does amount of phases have everything to do with a motherboard? Usually, but this is where brand name gets taken into account. For example, The majority of 2010-released MSI AMD motherboards with 4+1 phase or similar, heatsinked or not, were far from good quality. This is due to the utilisation of transistors that may not be properly rated, and driver chips not properly rated. However, take the Biostar TA890FXE, it comes with a similar 4+2 power phase. High amperage rating per transistor; completely rock-solid. It should be noted that an 8+2 phase system may not necessarily provide any more current than a 4+1 phase if the amount of amperage available to the transistors per phase is the same; however, the 8+2 phase system would still do so with more efficiency, stability, and with less heat output. 4+1 systems or less on CPUs can be particularly risky due to the fact that each transistor must be capable of outputting more current and heat. Sometimes these will also use cheaper transistors as well. This is why you normally see motherboards with low phase count failing (i.e. catching fire, frying, overloading), often on motherboards from only certain manufacturers or certain particular motherboards.Now, mosfet quality can be hard to understand.

Phase count can still matter. Most of the culprits for VRM failures are the lower end 4+1 phase and 3+1 phase motherboards that aren't equipped to handle processors that consume lots of power and may be overclocked. Failures on motherboards with higher phase counts have been relatively infrequent - so infrequent that it can be called rare.

Oh, found out something about Z68 with IB. You need to have a Sandy bridge CPU to update BIOS so you can use an IB CPU on a Z68 board.

I have a 4+1 and I Oc to 4.5 GHz with temps under 60C under 100% load.
