well...
keep in mind that mobo for AMD costs less.
and when buying an AMD cpu, You buy a memory controller, since its integrated into the cpu.
So the price of processors shows nothing.
performance / (mobo price+ cpu price) = what You get for Your money.
in my opinion, msi k9a2 or asus m3xxx mobo + the 125 W tdp 9950 phenom is a winner.
