It's utter gash if you don't use your pc like a tablet and actually want to work on it.
Get Win 7 pro, the only thing Win 8 brings is faster boot times, otherwise it's poor.
What are you dribbling on about?
I suspect most of the people here who've installed Windows 8 on their desktop actually USE it as a desktop machine, myself included.
Apart from the Modern UI that I see for about 3 seconds on bootup, I spend most of my day "working on it" without any issue.
The Modern UI does nothing to hinder using the machine as a full on desktop.
