I own an ASUS RIVE and I can tell you I've never seen a BIOS with that many options to tinker with. It's absolutely amazing, but you need some time to know what all that stuff means. I mean 6 pages of memory timings alone... But the ASUS BIOS has a lot more of these nice features, like for instance the PCIe lane simulator, where you can select which PCIe slots you plan to occupy and the BIOS tells you right away how many lanes which slot gets allocated. Very cool! But one thing that really (literally) 'sticks out' (pun intended) is the OC-Key. A hardware dongle, which you can hook to a DVI port on your GPU. This gives you a nice overlay on your screen displaying all the interesting stats (voltages, temperatures, ...) on screen, hardware based, without installing any software... AND you can control your overclock right in that on-screen display using your normal keyboard (just switch it to the OC-Key using a button on the ATX panel). Voltages, BCLK, multiplier etc... all this is configurable while your PC is running without a need for additional software. VERY NICE! This is probably biggest advantage the RIVE has against its rivals like this ASRock board.
