first : when next year 2003 , amd & intel produce cpu 64 bit but now we use software 32 bit , if we want to use old software (32 bit) should i buy new one cpu 64 bit or is it compatible with 32bit software ?

second : if i want to buy one first what i should buy between duron or xp ?
The new AMD 64 bit cpus are *supposed* to be backward compatible, and I *think* that Intel's aren't.

If you're buying one now, probably an XP. Durons are the budget chip. ;)
The Clawhammer (64-bitcpu) accelerates 32-bit code up to 10% faster than the previous Thoroughbred processor (Athlon) at the same clock speed. When you run 64-bit software, a larger 25% boost will be seen in almost all cases.

As for waiting, I wouldnt wait unless you are real despirate for x86 64-bit technology. Although, the Clawhammer will be in the desktop market, expect to pay lots for it. The ram alone will cost you a fortune for DDR400, unless you decide to go with DDR333 which will be value ram at the initial release of Clawhammer.
