Bootcamp

Yes.

 

No it will not run at its best because the hardware is designed specifically for Mac OS X not other operating systems. Other operating systems will run on Mac hardware but they are not optimized for it. For example, when in bootcamp I don't think you have access to the integrated video card.

 

Yes, under bootcamp Windows will have full access to the NVidia GPU. Since the main hardware is fairly standard, Intel CPU and controller, NVidia GPU, it works pretty well under Windows. Apple's drivers for the trackpad under Windows aren't as good as under OSX, but it works.

Battery life under Windows won't be as good as OSX because of driver optimization and because you use the NVidia GPU full time, rather than switching to the Intel GPU.
