want to upgrade the cpu in my gateway laptop and know how to do the mod but is $250.00 the cheapest price i am going to find on the 3.06 ghz extreme processor? its the x9100 i believe p_socket. also is this too much processor for the stock cooling system of this laptop p7815u. i will be using a laptop cooler but will i be able to use this processor when cooling pad is off. like on battery power. i have seen this mod performed on you tube but believe i would get more believable info from the forums. so anybody?
