Limit resources available to query in SQL Server

Question

I want to limit the system resources available to queries run by specific users in SQL Server 2008. Some queries are seemingly running away with all the resources of the machine causing the server to become unresponsive. My thought process is that if there is a way to cap the amount of resources (mem/cpu cycles/bw) a query can grab, this problem would go away. Is this possible? Are there better techniques to accomplish this?

This is MS Sql Server 2008,

If you're running the Enterprise Edition, you could take a look at the Resource Governor.
