"Also I have one more question if any one can answer it- I am replacing my current amd cpu + mobo. Does this do anything to my hard drive or save files?
well actually, yes..since windows only recognizes your components upon installation. when you change your mobo, you have to install new OS for that OS to recognize again your new mobo..well you can always choose not to format your hard drive when installing a new OS, though those old files of your old OS will be there, but it will not do any harm, it'll just cost your space, or simple just delete that old windows folder. that's more convinient. but for assurance, just backup your files, format your HDD then install your windows 8 ^_^
