I've been hearing that the new windows system will run on 64 bit processors since its going to be a 64 bit program. Will it also run on the old 32 bit systems or are we all going to have to upgrade in the near future? I ask this cause I just built a new system with a 3.0E GHz P4 system and I usually dont upgrade for 3-4 years. My last system was a 750MHz athlon! I try to beat the dead horse, hehe. Anyway, was just curious about what you all think may be the benefits and all that about the upcoming change.
