HotHardware.com posted a quick overview of 3DMark Vantage

Futuremark has just officially unveiled the latest version of their 3DMark benchmark suite, 3DMark Vantage. Like PCMark Vantage which was released a few months ago, this latest version of 3DMark was designed for testing Windows Vista-based systems. This latest version of the 3DMark, however, is specifically bound to Windows Vista because it uses some advanced visual technologies that are only available with DirectX 10, which you may know isn't available on previous versions of Windows.
