Hello all, I have ASUS P4B motherboard and it says that it supports Up to 400MHz system bus, what will happen if I install a 533MHz CPU on it? What are the disadvantages? Will I see a noticable difference in speed and performance when I switch from P4 - 1.6GHz to 2.4GHz ? Does a larger L2 Cache size means faster performance ? for example; 256kb and 1mb ?
