I prep'd for it so I'm going to do it, dammit! I prepared on and off for a week: researched, went through the steps and what to expect in my head, learned possible snags and their fixes (from other people's first-hand accounts), prep'd what I needed to use, backed up drivers and my files, wrote down my key and printed out my step-by-step notes. It took a while but I was ready (and pumped). August 5, 2015: Clean install of Win 8.1 via bootable USB. Success! There were only 2 things that my notes didn't cover: There were multiple one-time boot options on my mobo (press F12 to get to this boot menu on GA-A75M-UD2H). There were 4 choices for USB. Obviously, USB-Zip and USB-CDROM were out. I thought, "Oh, USB-HDD but what is this USB-FDD?" [Six minutes later...] Ok, not FDD. Should've went with my gut and picked HDD the first time but no harm done and lesson learned. Uhm, yeah, pick USB-HDD. NOTE: The bootable USB was easily created with Window...
