What does it mean or differ from the 65nm ? and what is meant by 65nm and 45nm ? beacuase dual core 2 uses 65...! i need to by a new desktop so do you advice me to wait for this 45 processors and geforce 9 coming this november ?

Answer 1

Well getting into the actual engineering of it is a little out of my depth, but to put it simply, 45nm is better, it will consume less heat, which should allow higher clock speeds and better overclocking. As for shoud you wait, there is always something better coming along, if you need a computer now, go ahead and get one, if you can stand to wait, then wait.
