The price difference is negligible.
I haven't been able to find (m)any comparisons between the two, which is why I'd like to know which one you'd suggest and why. I'll be running linux, probably ubuntu 12.04, so I'm not planning on doing any gaming.
PS. Sorry if this is in the wrong sub-section, but for some reason it wouldn;t let me to put it in the general motherboard one.
I would get the ASRock Z77 Extreme4 because it has a better power phase design (8+4) which will make for better overclocking. It also has a few more on board features and costs less. They're both great boards but save yourself $50 and get the ASRock.
Could you please post the link(I'm guessing it won't be only for motherboards so it could be useful.)?
It seems that the drivers aren't necessary for the motherboard to run under linux... Who would've thought... I'm guessing since it was supported in 11.04 it'll be supported in 12.04 as well.
I still need to do some asking around to make it certain, but thanks Nikorr!
