To begin to witnessing the effect of 64-bit processing, you need a large CPU cache -- >=1MB, and a large amount of very fast memory -- >=2GB, wider and faster Buses, and most definitely SCSI subsystems. When we talk 64-bits, the amount of data we are manipulating is very large. The speed of manipulating/processing such data is not the problem. The speed of moving and storing such data is were the problem lies.
You better have a pretty souped up workstation to even begin thinking about 64-bit desktop. I'm talking gigabytes of Dual DDR2 RAM, SCSI RAID, the fastest processor in the market, and chip sets that supports > 800MHz FSB. Then we can begin talking 64-bit computing. I agree with Intel when they say 64-bit desktop computing is still way off, except of course you are a power user or gamer.
