Hey Frens! Wats d difference between d newly launched Intel Pentium D Dual Core Processor and the Pentium Extreme Processor? I understand d 'dual core' concept. Any other difference? And if the Pentium D is on a 64 bit architecture, how will it affect the performance of the computer on which it is installed? Will applications designed to be installed and run on the 32 bit platform, work succesfully on a 64 bit platform???
