I don't think the response was referring to AMD chipsets, it was about using AMD CPUs, which are fine under the different versions of LMCE, but with the 0710 betas, now allow native 64bit mode as well. This works just fine. As for the experiences of various chipsets, you would be well to do some searches on these forums and particularly the wiki. The mobo you mention for the MD is an ATI Radeon video subsystem, so that is what you should search for.
