Saw on Anand's that French website x86 Secret has posted their full review of Athlon 64 & FX processors, they also happen to be comparing against Intel recently unveiled P4 Extreme Edition that features a generous amount of secondary cache.
Unfortunately however the article is in French, although you should still be able to understand some of the content there thanks to Google's rough English translation. In the worst of the cases you still have the charts and comparison tables to look at until other sites come up with their reviews tomorrow, enjoy.
