Let me make clear for you
Hardware 32bit 64bit
RAM 1GB 1GB
Both speed are ALMOST SAME.
So here again
Hardware 32bit 64bit
RAM 4GB 10GB
Now 64bit beat 32bit because 32bit's max to 4GB.
That's why Universities, U.S. Government and NASA as webexplorer said need 64bit for add more ram and hdd in future and dont need to replace whole computer system.
I believe NASA need more than 1TB of ram for server.
