- OS X 10.6 Snow Leopard?
- Windows 7 Professional 64-bit?
- Windows XP Professional 32-bit?
- Ubuntu Linux?
Which OS?
The short answer is: the one that your hardware and software are fully supported on.
The longer answer is that you may have to painstakingly check all software applications and hardware devices to ensure full compatibility with the desired Windows, Max OSX or other OS version. If you can and if your hardware and software support it, go with the latest 64-bit version of the OS. Many of the current releases of popular applications (such as Adobe Premiere Pro and After Effects CS5.x) only work in a 64-bit OS.
