Do you think this is still a valid argument? All the systems are win7-32bit PRO and should I pick a 64bit for the new 'server' computer and throw it into the mix?
I run 64-bit, I know that most programs are now able to run in a 'compatibility mode' if there's issues running in a 64-bit environment. I haven't run into this problem with our 2008 SBS 64-bit server yet. Running a 32-bit server will limit your RAM upgrade options substantially(4gb maxed out vs virtually unlimited for 64bit).
