Hi Cindy, I'm actually just starting to play with the inSORS software on a new Windows XP Pro x64 machine. I haven't put the software on it yet, but I can tell you that the largest hurdle that you'll face is making sure that you have 64-bit drivers for all the hardware. Since the x64 versions of Windows use the 64-bit addressing scheme and various other fun innovations, any hardware that you have MUST have a Windows x64 driver, which is usually on the manufacturer's website for the device. I'll be beginning my hunt for such drivers soon and I can let you know how it goes. But I'd expect a fair performance boost for AG stuff under the 64-bit OS and hardware.
