I think what AMD need to do now is to start an agressive means of pursuing software engineers, games programmers and benchmark writers to start using a better compiler which is well optimized for their processor (PathScale Compiler @ pathscale.com). Even if they need to start carrying bags full load of $$$ to pay those guys to do so. It's not against the law, INTEL is doing it. If most games are recompiled with AMD optimized compiler I think Intel CPUs will suffer even more setback than it's apparent now.
Those of us who write and compile scientific programs know quite well that Intel CPU are just Inferior to A64 if you have the right compiler at your disposal.
