I'd imagine that a 7970 driver for 32 bit windows would be basically worthless. Since the non-server versions of 32 bit Windows only have 4GB of address space, one 7970 would take up 3/4 of it and you'd have a whopping 1GB of system RAM available for use. If you added a 2nd card, you'd surpass the total available address space. You'd either have no system RAM available for use, or you just wouldn't be able to use more than 1 card.
