Hey try doing your homework before shooting your mouth off.
There is more than one factor in determining the performance of a CPU. The first, which every newbie is familiar with, is the clock speed. There is another major factor, that is less well known. What is amounts to basically is Instructions/Clock. AMD has boosted the number of instructions/clock cycle on their XPs.
This means that although the clock speed may be lower, the instructions/clock is much, much higher. Intel may be using a higher clock cycle, but they are neglecting the Instructions/clock.
Look at any established benchmarks comparing the two. You'll find that AMD chips outperform Intel chips on nearly all comparisons except memory bandwidth.
Mhz for Mhz comparisons mean nothing. Performance is where it's at.
As for overclocking, XPs are easy to overclock; you just have to join the L1 bridges. Granted, it is not as easy as before, but now only requires one extra step.
So again, do your homework before shooting your mouth off. It is obvious to me that you are little more than a FSB newbie with no idea of how CPUs really work.
