Biggest bang for buck amd processor.

Hi,

I was totally confused looking at the AMD model line for 32 bit the
other day. Different front side buses and different cpu cache sizes.
Of course the famous amd rating system is confusing to me at least.

Does anyone know a site that has ratings for the best bang for the
buck amd 32 bit processor? Best price/performance ratio.

Does a 512k cache really make a difference? Does a 333 FSB bus really
that slower than a 400 FSB? I'm looking at the athlon 32 bit lineup.

Thanks,

Alan
