Windows 7 or 8

[Synge]

I have a surface pro and Windows 8 works really well for that. That being said, I'd hate using it on my desktop, Wimdows 7 just feels better for what I do (music production and gaming). I can't say much in regard to potential performance improvements or anything like that, but if you're building a desktop PC for gaming, Windows 7 just feels right, go with that and upgrade to Win 9 later if you feel the need (and if they don't **** it up).
