To my knowlege they don't have any programs that will use quad CPU's or 64 bit software. If they do I'm sure they will run just as good on a dual 32 bit system. For 99% of users 3.3 gigs of RAM is enough and I am testing the 64 bit windows 7 which I find a little slower in some of my programs. It sounds to me that the hardware is about 4 years ahead of the software. I'm posting because maybe some of you know something I don't and I'm here to learn.
