K, not every AMD is better and in most cases not even close to the P4 3.4E. there are comparable processors in AMDs, particularly the 64 or FX series. The first thing you need to decide is your cpu interface, AMD has Socket A (462), 754 and 939 (and the quickly dying 940) and Intel PGA 478, 775. The older XP series using socket A are yesterdays news. the really just don't have the mhz or the FSB. the newer 754 or 939 using 64 bit instruction take advantage of an incredible 1200 to 2000 mhz FSB (front side bus), allowing them to communicate with all the components at an incredibly faster rate than the newer P4 800 or their older counterparts at 533 or a crawling 400. Also, many chipset designs for the AMD take advantage of the FSB and 64 bit instruction. this isn't always the case. ALWAYS research the chipset architecture b4 u buy the mobo.
