Mac mini(Geforce 320m) w/Bootcamp

Greetings,

I am interested in a mac mini with the Geforce 320m gpu.
I will be running it as a 64bit Windows 7 machine via Bootcamp.
1.Is CUDA supported on the Geforce 320m?
2.Double precision?
3.Fermi architecture?
4.64bit Windows 7 drivers avaliable?
5.Any experiences with similar setup are greatly appreciated.

Thanks in advance.
