Dumb question. I have the Core 2 duo processor from pentium...and is the core 2 is that 32 bit or 64 bit. Is the 32 or 64 bit ability is that dictated by the processor or Vista? If it is dictated by Vista and the core 2 has the abitility to do 64 bit is there anyway to change it to 64 bit without buying a new vista disk?
