With regards to the difficulty of fitting AMD XP proccessors....
Yeah, the Heatsinks are a real pain to fit.. Require quite a bit of force to get the clips onto the motherboard mount. Actually putting the processor onto the board is a doddle, just lift the clip... drop it in close the clip.. and get that tricky HS on. Don't let that put you off though.. it really isnt a problem, just requires perseverance
