I was wondering which one you guys would buy. I know there is a big debate over the new dual cores, so I am looking for the one that will be the best quality, and one that I can use for a while and not have to upgrade for sometime. Mind you, I will not be gaming, I am only looking for performance running many programs at the same time such as itunes, aim, word, outlook, etc, and encoding and dvd decrypting. Please give me your recommendations and why and let me know some good accompanying parts such as mobo, heatsink, ram etc. Thanks for your help
