NVDA, Windows and Bootcamp.

Hi guys. It's been a year since I have been using my Mac and loving it. I tried to avoid Windows by getting used to Mac and finding software for it. But unfortunately I'll have to work with one financial ap which does not support Mac. So the day when i have to install windows on my MacBook Pro has come. I'm intending to use Windows 7 via Bootcamp utility, and NVDA as my screen reader. As far as I know Bootcamp is accessible like all other Apple applications, so I'll need sighted assistance only for installing Windows itself. But I don't know much about NVDA. How it works with Windows? Is it appropriate to compare it with Jaws? Which voices it uses and whether it provides support for languages other than English? Please share your experience. Thank you in advance.
