A classic,this is one for the all time most dumbest questions EVER asked,I'm currently selling an AMD Athlon xp 2200 cpu on ebay,this is gospel btw,I was asked if this would fit in a Pentium 4 socket 478 Motherboard,after I fell off my seat I calmly replied,no,you need a Pentium 4 socket 478 cpu,where do these people come from
