I don't have any personal experience with Asrock mobos, but I've never had any issues with Asus. I just bought the FX-8350 and am running it on an Asus Crosshair V Formula-Z board. So far it's absolutely amazing. If you're looking to build a gaming rig, I highly recommend the Formula-Z unless you need the more durable TUF setup that the Sabretooth has.
