"First of all (and this shouldn't come as a shocker to anyone) the next
generation 3DMark will be Windows Vista only, and will require DX10
compliant hardware. You may ask: Why no fallback to DX9 then? Well, we
already have a Vista enabled DX9 benchmark (3DMark06) and the last
three 3DMarks have all been DX9; 3DMark03 has one test which requires
SM2.0, 3DMark05 requires SM2.0 for all tests and 3DMark06 uppers the
requirements for two tests to SM3.0."
