Why?
I don't mean that to sound condescending, i'm just asking why you're choosing that range of AMD. Is it budget? If not, i'd seriously consider the Intel core2duo range. Much better than AMD's offering across the board.
I don't have a recommendation on board, cos i just wouldn't choose AMD, sorry.
Also if it is budget, you need to say, otherwise folk might spec up an almighty megabucks model that you can't afford.
