Ah yes that's what I meant when I said it used the Vista kernel, so far I haven't heard any real major complaints about Windows 7 unlike Vista.
As for a clean install, I agree. Even when the option is available I would say that it's always better to back your data up and then perform a format and a clean install. (Oddly it was advised that Macintosh users install Snow Leopard as an in place upgrade).
From the specifications that you recommended for an install of Win7, it seems like it will work just fine on any recent system since duel core processing and 2GB RAM is the standard in decent machines.
Despite my very limited need for Windows, I will keep an eye out for news on how DX11 turns out.
If that’s what you meant, then I have to say yes, it’s faster than any other Microsoft OS that I have ever used before. Despite being extremely “graphical” its overall impact on a computers operating/CPU speed is limited (comparative to Vista, XP).
This being said, if you have a tone of shit on your computer that is initialised during start up (MSN messenger, Steam, Curse Client etc) then it might slow down a tad. But this is the case will all OS’s.
