"Our test system consisted of an Intel Core 2 Duo E8400 clocked at 4.00GHz, an ASUS P5E64 WS Professional motherboard, MSI 9800GT 512MB graphics card, 2GB of OCZ DDR3-1333MHz RAM, and Western Digital WD1600JS-00MHB0 160GB SATA HDD. With each distribution we had manually installed the NVIDIA 180.08 driver and Phoronix Test Suite 1.4.2. Per our standard testing protocol, each distribution was left in its stock configuration (though as part of that, SELinux is disabled on Fedora). The final i686 and x86_64 builds of Ubuntu 8.10 and Fedora 10 were each tested."
