Activation was going to be the biggest issue I figured... From memory certain Windows 8 installers (no idea how it works with images) pull the pre-installed key from the BIOS which would be fine for all the 8 machines if I could get that working but the 7 ones where the key has been rubbed of or peeled off (because clients can be idiots) could be the biggest issue.

I was looking at getting this done at my old job but never had time. I was going to do it via ESXI/VSphere and have a VM with Win 8, Win 7, pro and home of both to do the updates that I need to do and image from those installs.

Why not recording it raw with fraps then if quality is at matter? I really believe using shadowplay would work for you just fine. 1080p/50Mbps/60FPS looks so crisp you really can't find any better alternative. Your ssd can't be a bottleneck with this setup, 850 Pro is banannas fast, everyone would suggest you shadowplay after looking at your rig, unless there's some other reason you don't want to use it...

From what I know PWM fans can be controlled with software like SpeedFan or the like and 3pin are purely controlled off of voltage. Not as precise but still gets the job done 

Lol AMD doing driver fixes, pls .
 
For reals though, if it doesn't cost the same or less than the 980ti and these are legit they're in HUGE trouble, the 980ti Gigabyte G1 beats the Titan X in The Witcher 3 with full ultra with AA at 1440p by 7 FPS. I know 7 doesn't seem like much but 64FPS-71FPS on my 85hz panel isn't huge but it's still under the max refresh rate meaning I'll get the difference...
 
Not sure if this is only GPU boost because of the cooling or if it's as high OC as they could go.

You're talking about parts that can reach 100c, or 212 fahrenheit, the boiling point of water.  Of course it is going to be hot.
