27 Yes, and remember tomshardware doesn't test Gentoo Linux. Look at a
28 site like openbenchmarking.org.

33 Gentoo results are the most relevant, remember. The bulldozer kind of
34 sucks outside of Linux, and even Gentoo, and other benchmarks wont
35 show the results you would get. Highly threaded things kick ass on
36 the bulldozer, so I imagine updating with it would be fastest.
