Update: We are getting away from Identity primary keys and going to guids which are easier to insert in batches.
I hope you have also made these guids a NONclustered index. If not you will need to constantly be defragging these. It doesn't take very many rows of a clustered index on a guid column to exceed 99% fragmentation.
My recommendation would be to find another column to use as your clustered index.
--edit--
And unless this is a distributed system I just don't care for guids. They are exceptionally wide and a complete pita to work with. Debugging and such is very painful to deal with.
