From MSDN Article on Troubleshooting Performance Problems in SQL Server 2005

The following query gives you a high-level view of which currently cached batches or procedures are using the most CPU. The query aggregates the CPU consumed by all statements with the same plan__handle (meaning that they are part of the same batch or procedure). If a given plan_handle has more than one statement, you may have to drill in further to find the specific query that is the largest contributor to the overall CPU usage.

select top 50  
    sum(qs.total_worker_time) as total_cpu_time,  
    sum(qs.execution_count) as total_execution_count, 
    count(*) as  number_of_statements,  
    sys.dm_exec_query_stats qs 
group by qs.plan_handle 
order by sum(qs.total_worker_time) desc
