After having two Z-series MSI motherboards, my humble observations are: great value hardware wise, VRMs and stuff, but I got some remarks about their BIOS-es. Machines boots too fast, skipping some stuff, with or without "fast bios" enabled. Had to resort to PS/2 keyboard a few times to get into the BIOS as the 3-second hold power button wasn't on. They just leave me with something to be desired, I never had to do this with other brands I've switched. Also my AЕ-5 didn't want to work with my current MSI MB exactly due to fast skipping devices on boot, we will see if it will with Asrock. (could be the card itself, don't know yet).
