A week or two ago on a whim I decided to upgrade my PC, and visited the local Novatech store and bought all the parts for a new PC. I briefly considered a pre-built system from Scan, and the components they used heavily influenced my choice. The main choice was Sabertooth or Hero VI motherboard. I chose the Sabertooth - but I can't say why. I am using it with a i7 4770K and with the stock Intel HSF I got a 4.3GHz overclock (under stress). With a Corsair H60 fitted I get a 4.5Ghz overclock, albeit @1.3V core voltage - temps 80-90degC. I'm now considering trying water cooling for the first time, but mainly to keep the noise down. There are quite a few choices in the BIOS, and it took me a while and a number of YouTube videos before I figured out what to do to overclock the CPU. My main concern is the CPU core voltage control. After booting Windows 8.1 (eval) I run the ASUS utility to monitor temps and voltages. I chose MANUAL for CPU core voltage and entered 1.2V, so I was surprised to see 1.35V displayed for each core in this utility when running Prime (@4.5GHz). I have played with AUTO setting, but it is as if this motherboard has a mind of its own. I would be interested in the observations of any other owners. Also are there any other tweaks to eke out that final 0.1Ghz of overclock? Another question - although not specific to this motherboard - can I run two monitors from the on-board Haswell video controller? I don't play games and it would be nice to use the on-chip video in order to eliminate a video card and its (usually) noisy fans. The on-board video over HDMI gives a nice sharp picture on my Hyundai IPS. When I replaced it with a Nvidia graphics card over DVI, I was surprised that the picture seemed less sharp (going by the BIOS boot screen).
