Please read the big thread it's been coveredSnyder said:Something that you might want to keep in mind is that Intel only makes 32 bit processors not 64 bits. AMD makes 64 bit and when Longhorn comes out next year it'll only work on PCs with 64 bit processors.
Vista is 64 bit but it also has the option of being 32 bit I don't know how microsoft is going to make that work but think of it as when Windows 95 was 32 bit but also supported 16 bit. Vista is coming out next year and will support the current 64 bit processors and the new ones. Both AMD and Intel makes 64 bit chips....
