i've heard that windows 7 will come with both x86 and x64. i've always run x86, even though my processor is x64 compatible, because i only run 2gb ram, and i've always read that you really don't benefit much from x64 at that level.
but since i have to do a clean install when it comes out in october anyway, i am thinking about getting more ram and going for it.
what do i need to know? any advice? should i expect to struggle with drivers? is there a chance my hardware won't work? how can i prepare for this?
