You can export the execution plan from the buffer cache using this dmv. You can find many examples of the queries if you google this dmv.http://technet.microsoft.com/en-us/library/ms189747.aspx
Export the execution plan of a proc now and compare with when performance is slow.
Assuming your problem is all procs and queries I don't think this is going to make much difference. However it's a good tool for you to have in your arsenal.
Thanks for the link. I'l give it a go.
