The WinRAR results here are not really comparable, as the Mushkin XP2-9200 was tested with a 2MB L2 cache E6400 whereas the better results were obtained with our QX6700 with dual 4MB L2 caches - but note how much better the memory performed in the P965 based Asus P5B-E than in the Gigabyte N680SLI!
Doom 3
The Doom 3 results are also quite good, especially considering the processor difference - and the P5B-E again proved its mettle.
