Take your pick, wanna see what people think.
either will do what the other can do, only things different are ASRock still using legacy
PCI if you need that for an older sound/network card. both can overclock, both can
SLI/CFX, have 6 SATA ports and Intel LAN. i haven't used ASROCK UEFI, but i have
the Hero and it is straight-forward and well categorized. if you want red/black scheme,
its Hero, you looking for a blackout scheme, prolly the X3. as for cost X3 is a far better
value, but i use ASUS, Gigabyte and MSI all of the time and haven't reinvested time on
the ASRock products.
