Re: Fresh Install of Windows 7
Switchable Graphics is not necessarily a 'new' technology... but it's supported like it's still in beta. If you reload your copy of Windows 7, you may have an extremely hard time getting the correct drivers for your system. Not because of the Graphic Card, but because of the dual graphics card. It's a laptop manufacturer driver and not a GPU manufacturer driver. I would make sure that you have all the needed drivers for the cards and functionality before you decide to wipe the slate clean.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
