sql 2005 - The column was specified multiple times

  SELECT TOP(20) * 
    FROM (SELECT * 
            FROM [3D_Benchmarks] 
            JOIN [3D_Slugs] ON [3D_Benchmarks].Id = [3D_Slugs].BenchmarkId) AS tb 
ORDER BY tb.FPS DESC;

Я получаю эту ошибку:

The column 'Id' was specified multiple times for 'tb'.
