Maybe you should rename this thread as the "Official AMD vs. Intel Flame Thread".
If you are asking about Desktop processors from AMD and Intel, I would recommend the Athlon 64 X2s, if you plan to get your system now.
If you can wait, wait for 2-3 months, Intel is launching a whole new processor line, the Core 2s, and these will rock. Also, their launch will cause huge price cuts from both AMD and Intel.
So, I would recommend waiting, however, if you do want to get a processor now, get an X2 if you can.
