Most motherboards that have the hard drives running off of sata have the AHCI option. Even switching to a different motherboard with this type of interface enable will cause little headache, though you will most likely have to reactivate windows, you may or may not get by if the motherboard is identical I.E. swapping a dead motherboard for a good one of the same model.
As for the processor upgrade, if you have the latest bios in you should be good to go. I advise backing up your data in any regard just because not only is it a good idea, but will also save a lot of headache if the Sh** does hit the fan and you for some dumb reason have to re install the OS.
