D3D RightMark 1.0.5.0 Beta 4	Source: 3D.Rightmark.org

D3DRightMark is an independent non-commercial open-source graphics card benchmarking project developed by iXBT.com. It's called to help users estimate graphics cards performance and quality in synthetic tests and real apps, e.g. games. Synthetic tests allow estimating performance and capabilities of separate graphics cards subsystems in order to forecast their behavior in either applications, both existing (that is overall estimation of suitability and prospects for an entire application range) and developing, provided that a given accelerator demonstrates peculiar behavior under such applications.

The two individual 7800 GTX cards run neck and neck although this benchmark clearly does not like SLI.

Gun Metal 2	Source: Yeti Studio

Gun Metal 2 is one of the first benchmarks to take full advantage of DirectX 9 technology. According to Gun Metal 2, 2x AA is enabled by default on all videocards and the listed frame rates are average. Gun Metal 2 is not currently SLI compatible.

Gun Metal is a very weird benchmark, overclocking and SLI does not improve framerates one bit! Still performance at stock speeds in all resolutions is quite impressive.
