30 seconds on google will turn up page after page of independent tests showing that bulldozer is a failure. 30 more seconds turns up pages showing that the latest AMD stuff is barely comparable to sandy bridge in ideal circumstances, and gets crushed when compared to ivy bridge.
Please. Show me something that says that AMD has any relevance in any market that isn't less than 75 dollars. Even if you can, it's frequently worth a couple of extra bucks just to get an LGA 1155 socket because it gives you more flexibility to upgrade if you need to in a year.
