I recently got a Dell XPS 600 which comes with a Pentium D processor. I am moving my data and operating systems from an old Pentium 4 machine to this one. I am running Kubuntu 12.10 32 bit.
I know this can appear as a double question, but what I am requesting here is information about what makes my "64 bit" (apparently the Pentium D isn't a true 64 bit?) computer different from a 32 bit one, practically, and what that entails OS- and hardware-wise. I will point out two specific holes in my knowledge:
- Would I gain anything by switching to the 64 bit version of my OS, Kubuntu 12.10, considering my specific hardware/OS combination?
- Is it true that you have to put twice as much RAM in a 64 bit system?
