The following article from seomoz speaks to this:

Highlights:

- "70 characters is the maximum amount of characters that will display in the search results"

- "Place Important Keywords Close to the Front of the Title Tag"

- "Leverage Branding. Many SEO firms recommend using the brand name at the end of a title tag instead, and there are times when this can be a better approach. The differentiating factor is the strength and awareness of the brand in the target market. If it is a well known brand, and it can make a difference in click-through rates in search results, the brand name should be first. If this is not the case, the keyword should be first."

Based on this you should keep the branding at the end and work on the up front content of the title tag. That content should be based on keyword formulations that are relevant to the page and targeted towards formulations that you have a chance of doing well with.
