It's been a couple of months since a major review site let slip a generally positive comment about an entire lineup from AMD but on Techreport.com:
"Generally speaking, AMD's Phenom II X4 processors appear to be slightly better deals than the Intel Core 2 Quad equivalents. Not only are they great performers for the money, but the Socket AM2+ and AM3 platform has a better upgrade path than Intel's soon-to-be-retired LGA775 platform. The Phenom II X3 720 is more of a mixed bag, since it's the top performer neither in single-threaded tasks nor in heavily multithreaded ones. However, the 720 is still a good middle ground between cheap quad-cores and high-end dual-core CPUs."
