64 bit processors allow much more memory in a single segment, but what about speed?if you were to run todays 32bit programs on 64bit processors would they run faster? and would it be possible to run 32bit programs on 64 bit processors? unless microsoft comes up with a 64/32 bit operating system. which they probably will. if so, will this be windows 95 all over again?

I replied to a post several months ago about a similar thing here.

I don't think that 32-bit programs are going to run any faster on a 64-bit processor although it is definitely possible to run them on a 64-bit processor. And microsoft definitely is working on a 64-bit O/S.

I am as excited as anyone to see this happen. But I still feel that the processor is the least amount of bottleneck in 99% of the applications that we run. What about hard drives? Notice how things drag once your computer has to start caching? The fastest processor in the world isn't going to cure that bottleneck. Even with SATA and SCSI, it is always data access where I am limited in what I am doing.

I would love to hear other peoples opinions though.
