Well folks so far we only have about 6 different board configurations. Statistically, not a very large sample to draw conclusions from but such is the situation.
I guess from the data in the posts, about the only conclusion that can be drawn is that the Athlon (unsupported) rigs are the best choice. Though with the number of samples taken the margin for error is probably +/- 50%
Thanks again to all those who've participated and if you wish to contine posting by all means please do so; however, the topic, sadly, no longer will be refreshed at this point, even though people still post the infamous "What system should I buy?" question.
I will create a final post with the numbers posted by everyone in a single one pager with a relevant title for easy searching.
