A1: For main workstation is 16 GB the optimum? Edit

Hugh performance improvements can be achieved by adding more RAM memory to the system, especially when working with large sets. However, due to the addressing limits of 4GB on a 32bit system OsiriX needs to run on a 64bit system to benefit from the added memory. This requires the 64bit extension to be separately purchased.

A2: Is 4 core enough or is it better value to get 8 cores? Edit
