So I currently run a I5-3570k I'm running the MSI z77a g43 currently on my computer. And have a asrock z68 extreme 3 gen 3 on the side. I know there is basically no performance difference from the 2 and I haven't been able to use the Asrock BIOS/UEFI yet. So as for overclocking which board is better? So far I'm having a very bad experience with MSI for vcpu adjustment is useless...(last product i ever buy from MSI) Anyhow wanna hear inputs with people with Asrock mobo. no problems overclocking? everything you change will it register and not register under auto?.
