I'm kinda new to this so... I have a quite old system (3 years old) and it kinda sucks recently my sister upgrade her system and she left me her old cpu (amd athlon 64 x2 6000) And it's a bit better than my current cpu which is an amd athlon 64 x2 5050e. So can I just change the "new" cpu with the old one without any trouble, and if there is trouble can I just change back to the old cpu? The system is really outdated so there is no need to say it.. I know.
check your motherboards cpu compatibility list and see if its supported.
It's is. My main concern is will I be able to change the cpu back if something goes wrong?
