Good point about the cars though.
Other than that, 64bit is the way to go.
No. Individual (as opposed to the entire system with all running processes) 32bit applications are by default capped at 2GB maximum memory. This is enforced in the header of the executable binary; and yes you can fix that yourself by setting the binary flag that tells the OS whether or not the application can (is allowed to) handle more than 2GB. CFF explorer will let you do that from a GUI.
