It should be absolutely fine, when you replace the processor the bios should alter everything, if not it's nothing a cmos reset shouldn't fix, have a browse through the manual but it should be fine.
As for the rest of your system, it should be fine, the only thing I would consider is using matched speed
RAM but all in all it should be ok
