It runs perfectly on all my machines except this one. If I can't use Freya then I will skip elementary all together and just use windows.
( The reason I want to use Freya is because I want to learn linux, but I am full of shait if it looks k@k then I am not interested and this is the first OS apart from OSX that actually caught my attention. )
( The previous version wont work either all my ubuntu based installs on this machine gets same issue )
The difference in looks between Luna and Freya are very minor.
Big difference is Luna is stable and works, while Freya is not.
If you want to learn then doing so on a known broken OS is like walking around with a loaded gun and your finger on the trigger.
Why do you have so many PC's and need all of them to run Linux? Switch some of them off or just leave them be.
Try turning hyper threading off in the BIOS (or whatever it's called on AMD) as the problem seems related to too many cores.
