I recently found out about the activity monitor in SQL Server 2008 (I know, duh, right?). The tab \"recent expensive queries\" helped me quite a lot.

    You can view recent expensive queries with this... I use it all the time, it has far more detail than Activity Monitor.

    NB: This is for cached plans only.

    SELECT TOP 10 SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1,
    ((CASE qs.statement_end_offset
    WHEN -1 THEN DATALENGTH(qt.TEXT)
    ELSE qs.statement_end_offset
    END - qs.statement_start_offset)/2)+1),
    qs.execution_count,
    qs.total_logical_reads, qs.last_logical_reads,
    qs.total_logical_writes, qs.last_logical_writes,
    qs.total_worker_time,
    qs.last_worker_time,
    qs.total_elapsed_time/1000000 total_elapsed_time_in_S,
    qs.last_elapsed_time/1000000 last_elapsed_time_in_S,
    qs.last_execution_time,
    qp.query_plan
    FROM sys.dm_exec_query_stats qs
    CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt
    CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp
    --ORDER BY qs.total_logical_reads DESC -- logical reads
    --ORDER BY qs.total_logical_writes DESC -- logical writes
    ORDER BY qs.total_worker_time DESC -- CPU time
