Cuda on Vista Vista 32 or 64 ?

How would we know that the vista we have is 32-bit or 64-bit ?
I have a powerful machine with 2 8800 Ultra GPUs on it. I’ve just downloaded Vista bussiness on it and will work on having Cuda on it …

Any help … directions ?

why not ask to google?

To see if your computer is running 32-bit or 64-bit Windows, do the following:

  1. Open System by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking System.
  2. Under System, you can view the system type.

Can’t you do the same as on Windows XP?

winkey + pause
