just slave the hdd from the old computer into the new one once you have the new computer set up. there are no ties between a hdd and the amd/intel chipset. you could even access files from a different windows version (ie. winxp to win7).
The only things you could not transfer over are programs that were installed on the original machine. the files would copy fine but most programs have extra data installed to the registry and other folders required to run. Photos (any "data" really) will copy just fine.
