for the pc. there needs to be 2 players in the game. point is that amd have had a good run. if amd 'soomers kick up enough of a stink amd might try harder on the bios front? like intel has been before, AMD are in a good position to sell their products now. on price/performance. bottom line is will they lose out on cpu sales if they dont upgrade older chipset bios's to accommodate a yet to be released 4000 series lineup? or is it in their interests to sell their 500 series chipsets ?
