This could be a duel socket mobo with 2 quad core K10s doing the benches.
Neg.,it's one quad core CPU with 2900 in Crossfire.

Here are the the estimated perf. of Quad Core K10 versus intel's equivalently clocked Penryn:

John says the Quad-Core Opteron systems had already been submitted to the benchmark organizations for testing. The results are all under NDA and will only be released on launch date, September 10, 2007. Because they are under NDA, he cannot reveal the actual results, but he gave us some interesting indications of how the Barcelona will eventually fare against an equivalent Intel processor.

* 20-30% better performance overall
* 170% better performance in some benchmarks
170% better in some benchmarks.
