ktolo, you have a point for actual use, however he did mention in the beginning we're all using the same RAM which can allow some direct comparison across all our motherboard review articles.
For my part, as I test a variety of systems, despite sometimes notable benchmark differences, there is little practical difference in the end-user experience. In the bad old days of single and dual-core CPUs, everything mattered at the margin; now I think that is less true. This may be why AMD still manages to sell CPUs, as long as the price is right. Intel may indeed run rings around them, but in actual use the difference doesn't feel that great.
