For our processor reviews, we use three different operating systems: Windows XP, Windows Vista and Gentoo Linux. Although Vista has been out for close to a year, we’ve encountered numerous issues with our benchmarking, so we use it only where necessary, which at this time is only for PCMark Vantage.

Windows XP Professional SP2
• Screensaver and all power-related options are disabled.
• All chipset/motherboard drivers are installed, in addition to GPU.
• Windows Update is called in if a specific update is needed.
• Internet is disabled.

Windows Vista Ultimate
• Screensaver and all power-related options are disabled.
• Welcome Center is disabled.
• UAC is disabled.
• Critical Windows Updates are downloaded, including a fix for the GPU.
• Security Center is altered to never nag about the settings.
• Internet is disabled, and Aero theme is enabled.

Gentoo 2007.0
• A minimal install of the OS is used, without a desktop environment.
• System is updated to latest stable versions. including the latest Gentoo-patched kernel.
• Internet is disabled.

No time demos are used in this review. Each level was manually played with the Minimum and Average Frames-Per-Second captured with the help of FRAPS 2.9.4. Each play-through lasts between four and six minutes. Because no time demos are used, the average FPS will vary in between runs, even on the same CPU, due to changing circumstances in the game. It’s for this reason that we play on each setting twice, then average the two. To cover the bases, both 1280×1024 and 2560×1600 resolutions are used, to see if benefits can be seen at either the low-end or high-end.

Below, you can view all of the games we will be using, as well as the settings used.
