Looking at building a new computer since my desktop fried the other night (6 yo). Anyway, can anyone gives pro's or con's concerning the Intel P4 ~ 3 ghz compared to an AMD 64 bit ~ 1.8 ghz. The P4 is 32 bit but has a higher speed, whereas the AMD is 64 bit with less speed. Does the 64 bit make a big difference where the processor speed of the AMD could be equevalent to the Intel P4? Thanks for the help.
