All core 2 duo and core 2 quad processors are 64bit. so centrino duo should also be 64 bit processor. i have a core 2 quad Q6600 and have installed 64bit kubuntu 8.10

& it's better with the 64 bit version?
its better enough to go through the work of downloading and installing again?
i get to keep my configuration is i decide to do it?
