just buy the processor and save yourself like 100 bucks... ur wasting ur money...its not hard at all... u just have to lift a little guard, take it out, line up the little triangles, and then pop it in and close the guard.
uh oh, i forgot about his heatsink as well... its not that tough... u will just need to take that off first, get rid of ur dual core - clean the old compound off the heatsink...do what i said above... then apply new compound across the cores like a + (SMALL AMOUNT), and then replace the heatsink, and boot.
